You could try to reproduce the error by writing a big file e.g.
dd if=/dev/zero of=deleteme bs=1M count=80000
or similar and watching high definition video on Youtube (1080p) or running a few
instances of glxgears. That triggers a gpu hang in my case after
just a couple of seconds.
In my case, the hang doesn't occur when using SNA (or a kernel < 3.7,
which isn't the case with your bug). I have this in my
xorg.conf:
Section "Device"
Identifier "Card0"
Driver "intel"
Option "AccelMethod" "SNA"
EndSection
Without this, every 3.7 kernel produces a gpu hang within max. 1 min.
