--- Comment #11 from dwagner <jb5sgc1n.nya at 20mm.eu> ---
I did some additional experiments to understand what is so special about the
"Othan" video that playing it causes amdgpu to crash relatively fast.

Since the only "odd" parameter of it is its "6 fps" frame rate, I tried
replaying other videos, first at their normal rate (like 24 fps), which did not
cause quick crashes, then at an artificially lower set rate - and indeed, that
causes fast crashing regardless of what video I play.

The framerate that caused the "quickest" crashing seemed to be 3 fps, running
> mpv --no-correct-pts --fps=3 --ao=null some_arbitrary_video.webm
was usually crashing amd-staging-drm-next within < 1 minute for me.


Just some random thought: Could the reason be some timed hysteresis in power
management of the GPU?
Would there be some possibility to lock the GPU on a specific power level to
then try if those crashes still occur?
