Comment 46 for bug 975083

I'm also struggling with this issue for a while now. I had the random crash during 2012, it stopped as soon as i stopped using Unity3D / compiz.

I'm not sure that it's completely related to this, but configuring VAAPI HW decoding in many applications (I've tried both mythtv and xmbc) triggers the gpu hang event quite quickly. The side effect is the crash of the related program as well...

I had some success with the latest xorg-edgers + kernel 3.5 for some time but it was not stable overall.

My HW configuration is quite plain (Asus P8H67-PRO / Intel i3 + integrated HD2000), the only specificites are a HauppageTV card (my configuration is a HTPC) and the HDMI output used as the main screen. This may not play a major role, though.
