Description Matthias Nagel 2016-11-20 13:24:39 UTC
I recently installed a new Radeon R9 380 and use the amdgpu driver. My dekstop suddenly freezes, no input (mouse, keyboard) is possible. I still can login via ssh from another box and run some commands but I do not see any error messages. Dmesg, .xsession-erros, Xorg.0.log, journalctl are all clean.

If I try to shutdown via ssh I am kicked of from the ssh session (obviously) but the box is is not powered off. Somewhere during the shutdown process the box gets stuck. All the time I still see the frozen desktop. The only option is to forcefully power off the PC by pressing the power button for 3sec. After a reboot there are no errors in any log.

I prevalently use amd64 stable with some exception, because amdgpu needs llvm 3.9 and this again depends on mesa 13.x.y. which both are still marked as ~amd64.

@x11, would you be able to give a hand here?
Comment 2 Matthias Nagel 2016-11-27 16:51:17 UTC
Some new information (probably not very helpful):

I re-compiled the kernel and put all graphic-related stuff into modules instead of building it directly into the kernel. My hope was I could recover from a freeze by unloading the amdgpu modules or at least get a glimpse of information about what went wrong if I tried unloading the amdgpu module.

After the next freeze occurred I tried the following steps:

(1) Logged in from another box via SSH
(2) systemctl rescue
(3) lsmod still reported that amdgpu was used by 36 processes, although no X11-related processes were running anymore, monitor still showed the frozen screen
(4) rmmod amdgpu killed the machine entirely, after that even my SSH session was stuck, i.e. the shell never returned to its prompt, any attempt to login via SSH a second time failed
(5) Only remaining option: forcefully power off the PC

After reboot: No error messages anywhere
Comment 3 Matthias Nagel 2016-11-28 08:41:11 UTC
Somewhere else somebody suspected a GPU hang that is likely caused by LLVM or Mesa. He asked me to set the environment variable GALLIUM_DDEBUG="pipelined 2000" for the Xorg process and for the compositor which is kwin in my case such that the radeonsi driver might detect the hang and dump some information about it in a file in ~/ddebug_dumps/

How and where do I do it? I use systemd as my init process and the the active service file is sddm.service. Presumably, I need to modify some unit files but offhand I do not have an idea which one.
Comment 4 Aleksandr K. 2017-02-03 11:01:49 UTC
I have the same situation on my laptop with integrated Intel video.
Random freezes. I'm working with additional monitor and freeze happens more times then I switch processes with ALT+TAB or with mouse on left upper corner.

Comment 5 Aleksandr K. 2017-02-03 11:35:21 UTC
Also, I can go to the shell with CTRL+ALT+F1 and only X process restart is working for me. Session restartedd and I can work again.
Reboot working only if I close all mounted devices and opened shell(on alt+ctrl+F1)
Comment 6 Matthias Nagel 2017-02-03 11:56:17 UTC
As written in comment #3 I have already created some LLVM/Mesa crash dumps and it is reported upstream. https://bugs.freedesktop.org/show_bug.cgi?id=98874

However, since the bug was assigned to the radeonsi group, there has been to progress. Perhaps someone else could poke upstream.
Comment 7 Matt Turner gentoo-dev 2018-11-27 22:45:12 UTC
Upstream driver bugs like this are really outside the capabilities of a distro to fix.
