(In reply to Andrey Grodzovsky from comment #6) > dwanger, how quickly is this reproducible ? With the above video playback test (which I should refer to as the "Othan" test, because that is the name of the song in the video) actually quite fast - never took more than 10 minutes so far to get to the crash. > A wild guess, what if you boot kernel with IOMMU disabled ? Add iommu=off to > grub command line. Tried this: No difference, two attempts with current amd-staging-drm-next, one with hw_update_mode=0 and one with hw_update_mode=3, both crashed in < 1 minute of replay. Interestingly, the "Othan test" can even crash the 4.13 kernel quicker then the usual one or two days of uptime I can get with that old kernel. There isn't really anything special with the video other than it being encoded at only 6 frames per second. And btw., the video replay crashes even with --vo=xv, so without mpv making use of opengl. Replay does not crash with --vo=null. In contrast, when I replay videos with the usual 24fps, this runs much longer without crashing.
