--- Comment #1 from Eugene Shalygin <eugene.shalygin+bugzilla.FDO@gmail.com> ---
Playback of WMV3 streams using UVD sometimes leads to computer hangs (see
below). After upgrade of ffmpeg to version 2.0 from 1.2 these hangs happen much
more often, almost every time I try to play a WMV3 stream after several seconds
of playback. 

Gentoo was porting UVD patches to 3.9 kernel, and I remember that in the time
of 3.9 kernel WMV3 deconding was producing correct images (and computer hangs
also). With current ucode and kernel 3.9 WMV3 decondig produces the does not
work also.

Hangs seem to be almost complete: SysRQ does not work, mouse pointer does not
move. The only thing that remains alive is laptop Fn key combsnations to turn
on/off backlit of keyboard and screen backlight. Screen backlight turns on
(after being turned off) by any key press. Screen picture disappears for 7-10 
seconds every 20 or 30 seconds in the "hanged mode" and eventually lead to
complete hang of the computer.
