Description Philip Raets 2018-03-20 14:28:53 UTC
Created attachment 138225 [details] journalctl Nouveau crashes from time to time, it happens when I open some jpg-files, tiff-files, when I maximize windows, when I am developing in Android Studio, ... It happens randomly, but a few times a day. I can login with ssh through my phone (because my desktop is not responding to anything, I can only move the mouse cursor around), and then force a reboot (which I don't like, because of running virtual machines and unsaved work) I've tried the patched kernel from openSUSE, but it still crashes. My system is an up to date openSUSE Tumbleweed x86_64 Attached is my last boot log from "journalctl -k -b -1" Thanks, Philip

Can you see if this patch helps? https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v4.16-rc6&id=da5e45e619b3f101420c38b3006a9ae4f3ad19b0
Comment 2 Takashi Iwai 2018-03-20 14:39:16 UTC
The tested kernel already contains the mentioned fix. This bug was created newly just because it asked so there.

(In reply to Takashi Iwai from comment #2) > This bug was created newly just because it asked so there. Err, I meant, this bug entry was created newly just because it was asked so in Bug 105174.
Comment 4 Philip Raets 2018-03-22 14:49:30 UTC
Created attachment 138286 [details] dmesg Today I installed kernel 4.16rc6 from opensuse Kernel Head, but my desktop already froze 5 times today. Attached is dmesg log
Comment 5 Pierre Moreau 2018-03-22 15:07:45 UTC
I’ll try to reproduce on my Tesla cards during the weekend (if I manage to solve some other issues first). Are you using X or Wayland?
Comment 6 Philip Raets 2018-03-22 15:58:36 UTC
I am using X praets@PRAETS:~> loginctl show-session 1 -p Type Type=x11
Comment 7 Pierre Moreau 2018-03-26 11:08:58 UTC
I don’t have a GT218 to try on, and my tests on a GT200 were not conclusive as I was unable to reproduce the bug; I tried opening a bunch of windows, resize and maximize them, open some png files and run OpenGL games. I’ll try to look at the patches that were merged in 4.15, see if I can spot an error there, but I won’t be able to help much more than that. If you could bisect the kernel to identify the faulty commit, that would be really helpful.
Comment 8 Philip Raets 2018-03-27 08:48:08 UTC
I updated tumbleweed to snapshot 20180324 (https://lists.opensuse.org/opensuse-factory/2018-03/msg00615.html) which contains updates for Mesa and I've updated the kernel to the latest build on openSUSE: praets@PRAETS:~> uname -a Linux PRAETS.boma.local 4.16.0-rc6-3.g2539ea5-default #1 SMP PREEMPT Sun Mar 25 11:36:35 UTC 2018 (2539ea5) x86_64 x86_64 x86_64 GNU/Linux So far I haven't had any crashes anymore, tried opening a lot of photo's, switching windows, maximizing windows, ... So far so good
