Description

Raven Ridge APU (2400G), no external GPU, linux-4.17-rc5, libdrm-2.4.91, mesa-18.1.0-rc1, xorg-server-1.19.6, xf86-video-amdgpu-18.0.1, libva-2.1.0, mpv-0.28.2.

Getting this error second time, so probably there should be a report about it.

During h.264 video playback via mpv --hwdec=vaapi --vo=vaapi I'm getting:

[Wed May 16 19:13:48 2018] [drm:amdgpu_job_timedout [amdgpu]] ERROR ring sdma0 timeout, last signaled seq=15362, last emitted seq=15365
[Wed May 16 19:13:48 2018] [drm] No hardware hang detected. Did some blocks stall?

and image is stalled, X cannot be killed. Nothing graphical is started except X & mpv.
