Probably. And that means I really haven't noticed.
How do I test video decoding? mplayer seems to work fine :)
What's the output of mplayer? Mplayer usually uses video acceleration
when it is available.

Subject: [PATCH] drm/radeon: do not hard reset GPU while freezing on r600/r700
family

Seems r600/r700 does not like hard reset while freezing for hibernation
(regression due to 274ad65c9d02bdcbee9bae045517864c3521d530 which itself
is a fix for hibernation on some GPU families). Until i can debug further
issue with r600, let just disable this for r600/r700 as they are very
similar family and bug affecting one likely affect the other.
