Subject: [Intel-gfx] [regression] 3.6-rc6, gpu hang with vaapi
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:

bd22dc17e49973d3d4925970260e9e37f7580a9f is the first bad commit But there are tons of patches inside it. How can i proceed?
If more information is needed, please let me know.
