There are some low resolution (1024x560, 1024x600) h264 movies that with R600_DEBUG=nosb hang GPU, but strange thing - uvd work with R600_DEBUG=sb with it!
It is seems a different issue and this: http://lists.freedesktop.org/archives/dri-devel/2014-January/052945.html helps here (it works with R600_DEBUG=nosb), thanks.
