Getting Linux to boot on Lenovo Thinkpad E485/E585
- Trying to boot 32bit Linux resulted in immediate reboots. No output before that happened.
-
Most Linux 64bit distributions can be booted by adding
noapic (not noacpi!)intremap=offivrs_ioapic[32]=00:14.0 ivrs_ioapic[33]=00:00.1 to the kernel boot parameters -
Recent Ubuntu (and most likely also Debian) based distributions need also the boot parameter
spec_store_bypass_disable=prctlspec_store_bypass_disable=seccomp. Maybe other distributions/kernel from 2018 will need this, too. Seems that with Ubuntu 18.04 kernel 4.15.0-33 this is no longer needed. So try this omiting this parameter, and check that all devices you need are initalized (-> dmesg), then try seccomp, which disables the mitigations for less code and if still devices are missing, try prctl.
- null pointer dereference in _raw_spin_lock
- speculative_store_bypass
- ssb_prctrl_set
- arch_seccomp_spec_mitigate
- do_seccomp
- SyS_seccomp
- do_syscall_64
- entry_SYSCALL_64_after_hwframe
Update
After more testing it narrowed down to amd_iommu=off and then to intremap=off
The final error is "timer doesn't work through interrupt-remapped IO-APIC".
2nd Update
When booting Ubuntu, there is now a stack trace during GPU initialization:

That's funny, a colleague had the same issue with systemd-udevd today on ouf our servers. With a completely different driver .
3rd Update (2018-07-29)
Ok, this is really a firmware bug, the ACPI IVRS table lacks at least one entry. Adding ivrs_ioapic[32]=00:14.0 instead of intremap=off is sufficient to make the system boot until Lenovo releases an UEFI update with a working IVRS table. At least UEFI 1.27 (2018-07-24) needs this override. And spec_store_bypass_disable=prctl is still needed for Ubuntu & co.
The clue is the line "[Firmware Bug]: AMD-Vi: IOAPIC[32] not in IVRS table". I decompiled the ACPI tables, started to read the AMD documentation, but in the end I just guessed the 32 from the error message and 00:14.0 from the lspci output and the Stack Overflow/Ubuntu forum entries. Interesting stuff, but too much to read in my little time.
What was helpful is the Linux boot parameter amd_iommu_dump=1 which will dump information from the IVRS table:
Resolving devid 00:14.0 was easy via lspci:
00:14.0 SMBus: Advanced Micro Devices, Inc. [AMD] FCH SMBus Controller (rev 61)
Sources/References:
4th Update (2018-09-01)
At least with Ubuntu kernel 4.15.0-33 spec_store_bypass_disable is no longer needed. At least for my e485. My assumption is that this was a kernel bug in the earlier kernels with Spectre/Meltdown fixes.. Anyway, if you cannot boot or not all devices initialize, try the option seccomp and if that does not help try prctl. The option seccomp disables less spectre mitigations than prctl:
https://wiki.ubuntu.com/SecurityTeam/KnowledgeBase/SpectreAndMeltdown/Mi...
5th Update (2018-09-07)
Just installed BIOS/UEFI 1.32 which fixes the keyboard issue. But Linux still needs the IVRS Table overrride.
I am currently testing the Dell Latitude 5495, which boots Linux out of the box, but has also a few warnings/errors in the kernel log. I checked their IVRS Table:
Compare the indexes with the Lenovo IVRS table. My uneducated guess is that these entries should be the same for all mainboards with (Mobile?) Ryzen processors as I assume (guess!! correct me if wrong) that these are CPU internal devices. Maybe the Lenovo IVRS entries are just off by one.
6th Update (2018-09-10)
Pilatomic in the comments pointed out that adding ivrs_ioapic[33]=00:00.1 solves a couple of issues, in his case issues with the SD Card reader. For me this works flawless for all my microSDHC cards, the only write errors I got were caused by ejecting the cards without unmounting them ;-) Unfortunately I have found no way to remove entry 34 via kernel parameters, the parser will only accept well-formed parameters.So you will have wait for Lenovo to fix this ACPI table. I think by now they should know how to fix this and it's not a big change. But perhaps they do not care for Linux.
Second Last Update (2018-09-10)
The story ends here for me. I just discarded all data on the SSDs, reimaged the NVMe with the factory image, cleaned up screen, keyboard, touchpad and case. And hopefully I will find a buyer for this fine notebook
Why not the last update? I hope somebody will notify me when Lenovo releases a new UEFI version which fixes the IVRS ACPI table and Linux distributions will work out of the box. Then there will be a last update....
Another Update (2019-01-11)
According to this comment the IVRS overrides may not be needed anymore. And there are additional settings which should be set.

Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
Did you manage to get it to boot install and everything in the end?
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
Yes, running Xubuntu 18.04 from 2nd SSD.
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
Thanks a lot. I got Devuan (Debian whitout Systemd) installed and working with your help :) Where did you learn about these parameters. I wish to learn more about that :D
After updating kernel and getting firmwares from github (the devuan/debian package is old) I got the graphic card working.
I got also a way to set the battery to charge when have less 40% battery until it have more than 80% using tpacpi-bat ( https://wiki.archlinux.org/index.php/Tp_smapi#2nd_option.2C_tpacpi-bat ) and the module that it needs "acpi_call" which is ready as a dkms deb in Debian and Devuan.
I only have three problems more to solve:
1- I can see wireless networks in Network-Manager, I can click at Connect, it ask me the password, I write it, and... nothing, it does nothing. I tried adding the ath10 firmwares from github but problem is not solved. Just in case I deactivated Kwallet-manager.
2- KDE doesn't ask me a password if I modify things in SystemSettings which need root privileges, so I had to run kdesudo systemsettings5 to run it as root and do that things.
3- Bright- and Bright+ keys and others don't work. I installed an aplication for that for thinkpads, and I have to test it yet. Or maybe thanks to acpi_call module I can associate appropiate commands to get that to that hotkeys.
Thanks again.
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
Hello Javier,
I am glad to hear that you got Devuan running, and good to hear that notebooks can still run without systemd ;-)
The issues you described are the reasons why I prefer Ubuntu flavours over Debian/Devuan. Ubuntu is not as "pure" as the Debans, and is more open to include firmware and other stuff that comes quite handy in getting the latest hardware to work, so 1+3) both work for me out of the box. 2) sounds more like a KDE bug not related to the hardware.
Making Linux boot was a lot of trial and error. First I tested multiple Live CDs, than I found out that the failsafe mode of clonezilla was able to boot the system. It ran quite bad with only one core and so on, but at least it worked. Then it tested removing various of the extra parameters of the failsafe mode to pinpoint which settings may cause the crashes. Very basic information for all these parameters, you can find at https://www.kernel.org/doc/Documentation/admin-guide/kernel-parameters.txt. Of course you need an idea what the parameters change. Replacing parameters like splash or quiet with nosplash & debug. The rest is googling, reading documentation, wikipedia and kernel code (or at least the named backtrace parts ;-)) , With this simple debugging I came to nolapi and spec_store_bypass_disable=prtctl on Ubuntu.
The big problem is that with this setting you will get kernel output very late, when CPUs, memory and other basic stuff is already initiliazed. To start earlier you will need earlyprintk=device[,keep]. The best logging is probably done thru a serial connection, but modern notebooks have none. So earlyprintk=efi,keep or similar must be used and output goes to screen. The ,keep continues logging on the early console after the switch to normal logging happened, most likely duplicating all output. The issue ist, the output is dead slow.. think of the thousand boot log messages coming in at 1 line per second. Arch Linux used a smaller resolution and was much faster, but the of course less information fitted on the screen. And so it narrowed down or amd_iommu=off and then finally to intremap=off. My current guess is that something in the ACPI tables is wrong or so, but I haven't looked further as I cannot fix anything there, I guess...
The big problem is/was that there are at least two issues, the IOMMU interrupt remapping and these spectre (I guess) fixes which crash some drivers..

Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
Yes 2 (and 1 maybe) seems some KDE or permissions bug. I solved wireless problem installing Wicd (a daemon+gui similar to Network-Manager). I known it since Network-Manager gave me problems in the past in my old laptop (it tries to monopolize network configuration and you cannot touch some values by hand XD).
Wow, great investigation ;) Thanks for your effort :D
So I only need to solve now the special keys problem.
Could you please post the result of this command so I can see which firmware packages (and their version) have you installed in your Ubuntu?: dpkg -l *firmware* | grep ^ii
And wich kernel version do you use ad the result of this command to see acpi modules used: lsmod | grep acpi
If you prefer not to post it here, you already have my email, since I wrote it in my two messages here.
By the way my EFI version is 1.24, there two upgrades with this changes:
Version 1.25 ( 2018/06/26 )
[Important] Optimize UCSI PPM_RESET command to EC.
Version 1.27 (2018/07/24)
[Important] [Important] Modify SPL/SPPT/FPPT to 8W when battery RSOC to 20%.
[Important] Added notify battery change event when battery RSOC<10%

Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
Yeah, NetworkManager is sometimes more PITA than useful. For another computer I use I still need a working solution how to tell NetworkManager to use the DNS Server DHCP gives. For some reason NetworkManager/Xubuntu insist on starting an own DNS server (mDNS?) and sending queries there. Which is quite bad as public DNS Servers of course do not know my internal addresses...

Have you an idea what SPL/SPPT/FPPT mean in this context? May save me googling ;-)
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
Thanks.
Try Wicd, it only depends in some GTK libraries, not Gnome ones (the wicd-gtk gui, there is also a ncurses one and one for use with commands for scripts).
The firmwares included in Ubuntu are the last available on github at 2018 february the 22nd. I downloaded from github a tar.gz with the last ones two days ago so are newer but I only copied the wireless card ones to my /lib/firmware. I am going to copy and overwrite all of them just in case (making before a security copy of what I have now).
About modules:
I have also loaded acpi_call for battery 40%-80% charging as I said.
I have also acpi_cpufreq loaded.
And "rfkill" and "battery" modules are here also used by thinkpad_acpi module.
Do you have any configuration related to acpi inside /etc/modules file or /etc/modprobe.d/ folder?
If not, after firwares copying i will try unloading extra modules I have, and if not success, I wil dowload a Kubuntu live, and if not Xubuntu 18.04 live (sames as you)
I formated the disk without loading Windows 10 not even once XD. I will try selling the licence. No, I don't know what that means. Google will tell us XD.
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
Linux was also the first OS i tried to boot, because I like to take a full disk image, so I can reset it any time to the state when it was new. It's pretty annoying if this does not work. I can accept that due to the latest hardware Linux can't be used as the desktop OS (graphics card troubles or), but I need Linux as a rescue, test & debug system. So at least console mode should work without any serious issues like non-working USB or network. It's a bad feeling for me to know that a safety net does not work.
When I find time I will test Wicd, if it needs only GTK, then it should work with Xubuntu.
/etc/modules is empty. The only file I changed is /etc/default/grub for adding the kernel parameters. You can find my /etc/modprobe.d/ folder at https://evilazrael.net/tmp/modprobe.tar.gz . Maybe there is something useful in there.
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
I don't get more logs with "earlyprintk=efi,keep" in /var/log/messages, only very slow ones in screen :S
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
That's the purpose of earlyprintk. With this parameter kernel messages will be shown as soon as possible, it does not generate more message. efi means that the messages should go to the screen. Serial is usually more often used, and you can log the messages on the receiving console. netconsole is a network capable alternative, but this of course requires the NIC to be configured. If the earlyprintk target the same where the normal kernel output is sent too, the ",keep" causes messages to shown twice. See earlyprintk in the kernel parameters file.
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
Thank you for your work.
I probably never would have managed to find all that out by myself, but with your help I managed to boot and install archlinux just fine. For me the kernel parameter intremap=off was enough to get it to boot.
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
Yes it boots but without "spec_store_bypass_disable=prctl" as EAzrael said it shows an error.
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
In my machine acpi_thinkpad module uses battery module because the kernel 4.17(available in Devuan testing ) supports new things in last thinkpads: https://www.reddit.com/r/thinkpad/comments/7yeytz/battery_wear_control_t...
Here https://patchwork.kernel.org/patch/10396271/ I have seen the route of battery things in /sys There is not force_discharge as says there, but there is the routes which content I can see:
cat /sys/class/power_supply/BAT0/charge_start_threshold
cat /sys/class/power_supply/BAT0/charge_stop_threshold
I see they are in 40 and 80 as I have set with acpi_call module and the perl script. System remebers it, great!.
Following suggestion on a comment for the reddit link I have writen
echo 45 > /sys/class/power_supply/BAT0/charge_start_threshold
echo 75 > /sys/class/power_supply/BAT0/charge_stop_threshold
Hopefully soon there will be more options and there will be a GUI that supports that.
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
Ping
If you want to test something new, replace intremap=off with ivrs_ioapic[32]=00:14.0 . This should do the trick. Everything seems to work fine.
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
Seems to work fine here too.
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
Hey, thanks a lot for the work. with ivrs_ioapic[32]=00:14.0 everything works fine for me. I also installed the latest UEFI 1.27 update, but it didn't fix the problem. We might need to wait for another update from lenovo.
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
The ivrs_ioapic[32]=00:14.0 fixed the boot for me on E585, however the keyboard lags heavily (typed keys show up out of order and there is a visible lag). Does anyone else have this problem?
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
I do have the keyboard issue as well. I installed Arch probably an hour after receiving my E485 but I was under the impression that the issue was there with Windows. I could be wrong though.
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
I just got an E585 and I see the same keyboard issue on the pre-installed Windows as well as on Linux. Letters come out of the order when typing at full speed. It seems that other people are having the same issue - check out this post on Reddit:
https://www.reddit.com/r/Amd/comments/99zyl4/just_got_my_lenovo_thinkpad...
"Another thing to note while I am typing this is that I am making quite abit of typing errors, not sure if its the keyboard or just me not being used to it. But it feels as if some keys register faster than the other, maybe its just me but most of the error mistakes got auto corrected by the laptop anyways."
Considering that there are multiple reports of this, it has to be either hardware or firmware (BIOS) issue? If this is an inherent problem with this model, I am considering sending it back and buying a different brand.
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
Funny, now I realize that I have the same issue with Windows on my e485. I thought I was too stupid to type on the keyboard. It happens so often that two consequent key presses are swapped and I thought that it was due to "timing errors" when typing keys from both hands.
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
I did some more testing on this. Windows and Linux are both affected. External Keyboard does not have this issue. On a German Keyboard the easiest to reproduce combination is e+r like in "center". Put two fingers above these keys the "r" finger slightly higher and then type, do this a couple of times. Some combinations with space and backspace are also affected. And right shift seems to trigger this too (I use right shift more often than left shift, never learned 10 finger typing).
First sentence is right, the other lines are the one where I am sure I did not type anything wrong, It took me many more tries as somehow it's hard to type correctly when you focus on the actual typing to make no errors.
(yes, forgot "langer" in the second last line)
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
It looks like there is another person on Redit with the same issue:
https://www.reddit.com/r/Amd/comments/9ajmr1/lenovo_thinkpad_e585_3dmark...
"As for user experience based stuff i do have an issue with the keyboard, not the best keys. Made alot of typos with it and it feels "slow" coming from a mechanical keyboard desktop user"
At this point I'm seriously considering sending it back and looking for another brand laptop w/ Ryzen. :-/

There's a beta Bios v1.28 that fix the keyboard issue.

Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
I managed to install Debian Stretch 9.5 netinst on my E485 thanks to you and the ivrs_ioapic[32]=00:14.0.
I tried many things before this with the latest BIOS update. Only your solution works on my side.
Thank you very much.
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
Thanks a ton for your blog post. I got my E585 up and running. I still run into some issues however.
The newest kernel I can boot is 4.15.0-30 for some reason. I was using 4.18 RC7 just fine for a while.. rc7 stopped working, 4.18.5 doesn't work, 4.19 rc1 doesn't work. Nothing really changed, it just quit working (Ubuntu Budgie)
4.18.5: https://i.imgur.com/yk1bXWW.png
Also can't seem to get the bluetooth working to save my life. I got it working one time, and quit working again after reboot. Not too concerned since I can upgrade the wifi+bt card if needed
I did a writeup with photos of internals of the e585 if anyone is interested. https://forum.level1techs.com/t/lenovo-thinkpad-e585-ryzen-2500u-vega-8-...
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
Hi,
can you revert back to the old kernel and boot the system? If yes, if you have syslogs from the failed boots (/var/log/kern.log* syslog* boot.log, etc) please send the logs to me. E-Mail address can be found here: https://www.evilazrael.de/content/impressum
Just ordered a Dell Latitude 5495 with Ryzen 7 2700U Pro. One of these two will end up on ebay in the near future.
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
I have a similar issue. After a fresh reboot, Bluetooth never work. I have to close the lid (Laptop goes into hibernate mode) and then Bluetooth is available once I return from hibernate.
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
Hey,
thanks for your work, arch linux just boots and it's wonderful.
however, I think I got a little problem with the graphics card:
powertop keeps telling me to have a discharge rate of around 10W (and thats too much i think).
also the radeon graphics card reports 100% usage all the time, acpi tells me around 4h total time remaining when at 100% charged.
-> this laptop should last way longer according to the lenovo webpage, especially when running arch and not windows.
did any of you guys fixed that the graphics card is not always used to 100%?
I blacklisted radeon and added amdgpu.dc=1 as kernel parameters
thank you in advance :)
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
ok, after some research I found out that my notebook won't use any cstates >= 3.
can someone report his powertop output?
or his turbostat output?
mine shows just C1 and C2 state
without using these the powersaving performance will be pretty bad :/
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
Not necessarily. Maybe AMD is at good at C-State 2 as Intel with C-State 6 or whatever.
I think this boils down to the ACPI tables again. I am new to this, but if I read the references correctly, Only C-State 1 and 2 are defined in the ACPI tables on the notebook. I check my 2 other AMD system which are running currently and none of them goes lower than C2. Okay, the other two are desktops ;-)
So I would need confirmation that Raven Ridge CPUs have states C3 and lower. Either somebody confirms this or I have to dig deeper into technical references.
Btw. check the last line of the man page for powertop. I would not put too much trust into this tool ;-)
Need to sleep now. And the keyboard really sucks until I get this UEFI beta update.
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
Found this at https://support.amd.com/TechDocs/55072_AMD_Family_15h_Models_70h-7Fh_BKD...
This is not for the raven ridge family. Need to find the same document for CPU family 17h.
My discharge rate bounces
My discharge rate bounces around just sitting at the desktop, from 18W down to 7W though most of the time sits around 14W, so just over 3 hours. That said looking at windows feedback/reviews the battery life is NO WHERE near what they claim on the lenovo site, the windows review I read earlier agreed this is about what you expect from this laptop?
4 hours - https://www.reddit.com/r/Amd/comments/9ibe0m/lenovo_thinkpad_e585_ryzen_...
Re: My discharge rate bounces
I did see another windows review saying between 3 and 4 hours but kind find it again at the moment.

SD card reader ?
Hi,
Owner of a E585 here
First, thank you very much for this page !
Saved me a lot of time !
still having an issue : i can't get the SD-card reader to work !
Anybody experiencing the same thing ?
Re: SD card reader ?
Hi,
please show me the last lines of the output of dmesg after you inserted the SD card. I got these lines:
[ 358.527941] AMD-Vi: Event logged
[ 358.527946] INVALID_DEVICE_REQUEST device=00:00.1 address=0xfffffffdf8080200 flags=0x0a00]
Looks like I have to tinker with the IVRS table again.
Re: SD card reader ?
I got this exact same message
Good, so I know for sure that it's not simply a defective reader (haven't booted Windows on it, so I wasn't sure)
Looks like fun times ahead playing with this, I've always avoided messing with ACPI, but looks like i'm not going to cut it this time !
i'll keep you updated if I find a fix
Re: SD card reader ?
Using your guess that IVRS entries might be off by one, I manager to get a bit further :
adding "ivrs_ioapic[33]=00:00.1" got the reader got the reader to detect my card, but i'm still not able to access it :

Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
Just simple add iommu=soft to the Kernel Opts, this is also the default value for Intel systems. Work fine on my Fedora 28 install with uefi and Amd-V enabled.
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
Any idea what the impact if iommu=soft is? The kernel documentation is not so helpful and I have no time to search through the code.
But maybe this is the solution for one of the last mysterious on our Intel servers. I constantly get the message that the SWIOTLB is full or so....
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
I tried this and fine fedora 28 installs, but suspend and resume don't work, basically once you suspend the screen will come back on but not the keyboard etc and so useless, have to force reboot.
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
As to eazrael's solution, this works to get mint 19 to boot, but I then let it auto partition etc and it fails to install with uefi errors trying to do grub install.
Re: Getting Linux to boot on Lenovo Thinkpad E485/E585
Seems to be a Mint 19 issue as Ubuntu Budgie 18.04.1 installs fine and doesn't have the suspend/resume issues that fedora had either.. so far so good..
Tempted to try MX Linux but meh, this is working...
