Hi, I get a GPU hang every time i play an mkv using mplayer -vo vaapi with 3.6-rc6. With 3.5.4 no GPU hang at all. I'm using xf86-video-intel 2.20.8, xorg-server 1.12.4 and libva-1.1.0 on Intel(R) Sandybridge Mobile (GT2+). On dmesg, i915_error_state and Xorg.0.log: [ 105.822821] [drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed...
