Screenshot of hung system

Hello,

I have problems with my Sandy Bridge GPU. It hangs randomly after some time. It
happens every 2-3 days. When I disabled RC6, I had a 20 days uptime without a
problem. Happens on 3.6, 3.7 and even 3.8rc6. The system is totally frozen when
this happens.

I'm using a MSI CR640 laptop with i3-2310M and
00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core
Processor Family Integrated Graphics Controller [8086:0116] (rev 09)
