I was too fast with closing this: It crashes with newer mesa, too, just
(subjective) less frequent.

Here's a log from mesa 19.0.1:

> [178793.032358] [drm:amdgpu_job_timedout] *ERROR* ring gfx timeout, signaled
> seq=12332054, emitted seq=12332056
> [178793.032362] [drm:amdgpu_job_timedout] *ERROR* Process information:

> [178793.032365] amdgpu 0000:01:00.0: GPU reset begin!
> [178803.262008] [drm:amdgpu_dm_atomic_check] *ERROR* [CRTC:47:crtc-0] hw_done
> or flip_done timed out

And from git (26e161b1e9):

> [ 7819.095648] [drm:amdgpu_job_timedout] *ERROR* ring gfx timeout, signaled
> seq=2652771, emitted seq=2652773

Not sure if the log is shorter cause of new mesa or new kernel (updated from
5.0.4 to 5.0.5).

Are you sure this could be a mesa bug? Just asking cause for me a hanging
kernel sounds like a kernel bug.
