I have the same problem, are able to reproduce it and have bisected
it, but the commit which git --bisect identified seems not to be the
cause.
root@wildsau linux-git]# git bisect good
6c085a728cf000ac1865d66f8c9b52935558b328 is the first bad commit

drm/i915: Track unbound pages
This is a quite nasty (3.7) regression. I have it on all of my three
machines and it drives me mad (3.6.x hangs my USB 3.0 port and 3.7 my
intel graphics).
Try to boot with "i915.i915_enable_rc6=0" and switch to SNA in your
Xorg.conf:
Section "Device"
Identifier "Card0"
Driver "intel"
Option "AccelMethod" "SNA"
EndSection
There are tons of this "GPU hangcheck timer elapsed"
messages on the net...
Good luck!
