--- Comment #18 from Jona Stubbe <linuxbugs at jona-stubbe.de> ---
I had this issue on my Acer Aspire 5750G laptop as well.

Vendor ID:             GenuineIntel
CPU family:            6
Model:                 42
Model name:            Intel(R) Core(TM) i7-2630QM CPU @ 2.00GHz
Stepping:              7

It also happened on hibernate (suspend-to-disk).

I'm using past tense here since, ironically, after installing intel-gpu-tools
(no kernel update), the corruption did not occur anymore, neither on standby
nor hibernate.  If it interests you, I have attached the reg dumps. 

A remaining problem is that resume seems to break the power management so that
the CPU core temperature, normally under 50° Celsius, skyrockets to over 70°C
in about 2 minutes, so that I have to restart my computer in order to not
endanger the hardware. (Is this a separate bug?)
