Trying to play h264 encoded video with mpv --vo=opengl --hwdec=vdpau results in
frozen video and the system unresponsive to key/mouse input.  System freezes
roughly 1sec into videos, although audio often continues.  Bisected to the
following kernel commit:

    ASIC function.

I tested mesa (git-227b1af866) patched with "radeon/vcn: fix mpeg4 msg buffer
settings" by Boyuan Zang, but that didn't fix my problem.  I also tested
today's pull request for linux drm-fixes-4.17, but the issue is still present.
