relevant dmesg output

New UVD VDPAU decoding of VC-1 and MPEG-2 causes some kind of corruption and
ultimately hang of driver and whole system on the next try (cursor can be
moving for some time, even SysRq can work a few seconds after X totally hangs
but then only power off works).

Few notes (using mplayer):
ffmpeg12vdpau:
MPEG1 causes no harm, only decoding is really bad (software decoding works)
MPEG2 seems to cause really bad corruption

ffvc1vdpau:
VC-1 seems to cause problems (like attached dmesg) but not hangs.  There have
been decoding artifacts too, but it is not the rule.

divx and h264 seems to work flawless, unless previous corruption happened.

Hardware is ARUBA - A6-5400K Black Edition APU (Radeon HD 7540D).  Since this
particular hardware seems to be problematic (#65254 #60389) it might be unique
to this APU.
