Comment 16 for bug 477915

I also get this crash quite predictably, any time I play AisleRiot Solitaire for much over 30 minutes.
I've compiled the relevant packages (xorg-server-1.6.4,xserver-xorg-video-intel-2.9.0) with optimization turned off and got a full backtrace of the crash (attached). The relevant bit of lspci:
