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.
