<pre>Tested today's current amd-staging-drm-next git head, to see if there has been
any improvement over the last two months.
The bad news: The 3-fps-video-replay test still crashes the driver reproducably
after few minutes, as long as the default automatic power management is active.
The mediocre news: At least it looks as if the linux kernel now survives the
driver crash to some extent, I found messages in the journal like this:
Nov 14 00:59:36 ryzen kernel: [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring
sdma0 timeout, signaled seq=22008, emitted seq=22010
Nov 14 00:59:36 ryzen kernel: [drm] GPU recovery disabled.
Nov 14 00:59:37 ryzen kernel: [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring
sdma1 timeout, signaled seq=107, emitted seq=109
Nov 14 00:59:37 ryzen kernel: [drm] GPU recovery disabled.
Nov 14 00:59:40 ryzen kernel: [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring
sdma0 timeout, signaled seq=22008, emitted seq=22010
Nov 14 00:59:40 ryzen kernel: [drm] GPU recovery disabled.
Nov 14 00:59:41 ryzen kernel: [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring
sdma1 timeout, signaled seq=107, emitted seq=109
... and so on repeating for several minutes after the screen went blank.
Will test tomorrow if this means I can now collect the diagnostics outputs that
were asked for earlier.
Some good news: S3 suspends/resumes are working fine right now. There are some
scary messages emitted upon resume, but they do not seem to have bad
consequences:
[ 281.465654] [drm:emulated_link_detect [amdgpu]] *ERROR* Failed to read EDID
[ 281.490719] [drm:emulated_link_detect [amdgpu]] *ERROR* Failed to read EDID
