Some games running using Wine with DXVK causes system to freeze completely (SysRq doesn't work). It happens only with DXVK and doesn't happens with WineD3D (which is, roughly speaking, OpenGL) so i suppose the problem is in the Vulkan driver. Reproducible in: * Astroneer and Breathedge (UE4). Just run the game and system will hang within a few seconds. * Dark Souls 3 and Sekiro: Shadows Die Twice. Run the game, start a new game and run a few meters, system will hang. Some other games causes system hangs as well, but i can't remember their names. My specs: GPU: Intel HD 630 OS: Arch Linux Kernel: 5.0.7 Mesa: 19.0.1 It happens with other Mesa versions too (i tried 18.0, 18.1, 18.2, 18.3).
Hi, could you please clarify - behaviour is the same for all mentioned games? Asking because we already investigating this report https://bugs.freedesktop.org/show_bug.cgi?id=110228 Which has also gpu hang + kernel hang.
Well, all games causes kernel freeze, but i don't know if gpu hangs. At that moment i only have Astroneer installed, and i can't find anyting related to gpu hang in journal.
then maybe try 4.20 kernel or older? Who knows - maybe that's only kernel related.
I tried different kernel versions (4.14-5.0 and iirc 4.9 too) and in all cases kernel freezes.
Created attachment 143917 [details] [review] patch to disable dispatches in anv Hi, thanks for the report. It looks similar to https://bugs.freedesktop.org/show_bug.cgi?id=110228 where UE4 editor hangs. In that case it is due compute workload however I still don't know why it hangs and why it hangs so badly. So to test if these issues are related could you apply the patch I have attached? It will disable compute workload; this may break how games render but I'm only interested in hangs disappearance.
Hangs disappeared after applying your patch. I only tested Astroneer yet, but i will also test Sekiro a little later.
Thanks for testing, then I can assume that the issues are related.
I tested Sekiro and it doesn't hangs with your patch too, so the issues are related.
