dmesg
With some movies gpu hangs are quite reproducable while playing with "mpv
hwdec=vdpau vo=vdpau" in fullscreen (1920x1200), in the same time "mpv
hwdec=vdpau vo=opengl" work fine there.
For me it is quite easy to reproduce this with such encoded video:
ffmpeg -i big_buck_bunny_1080p_surround.avi -vf scale=1024:576 -c:v libx264
-preset medium -x264-params keyint_min=23 -c:a copy output_1024_576.mkv
Mostly it requires less then one minutes of playing in full screen for GPU
hangs.
I suppose that problem is rv730 specific, as I can not reproduce it with rv740
(but it PCIe and work with CPU which is mutch faster).

Most likely the name of the problem here is AGP. We already tried a couple of different workarounds but it is quite hard to get fully stable with UVD. Try to disable AGP with radeon.agpmode=-1 and see if that helps.
No it does not change it, I think it more likely size alignments related issue. If I change monitors video mode to 1366x768 (16/9 same as video 1024/576) it works in fullscreen too. More clearly would be a 1920x1080, but I was unable to set cvt 1920 1080 60 mode (screen corruption).
Ok, well that's a bit strange. Does "mpv vo=vdpau" works? E.g. VDPAU output, but with software decoding?
A complete shoot in the dark, but please try to disable semaphores by just returning false from uvd_v2_2_semaphore_emit() in drivers/gpu/drm/radeon/uvd_v2_2.c. Otherwise I'm running out of ideas what that could be. The only other explanation I have is that the added load of UVD+displaying at a certain resolution is crashing the GFX block. But I have no idea why that should happen.
bool uvd_v2_2_semaphore_emit(struct radeon_device *rdev,
struct radeon_ring *ring,
struct radeon_semaphore *semaphore,
bool emit_wait)
{
return false;
}
Same things.
