Last known good: 3.3
Bad kernel: 3.4-rc1
Subsystem: power management/suspend/dri(intel)
When I resume from suspend to disk then system hangs on this screen:
http://mrutecki.pl/download/kernel/3.4-rc1/suspend_resume/DSC_5479.jpg
It does not help SysRq keys. Only I can force power off by hold power button.
Dmesg:

Likely a known regression, ppgtt support broke hibernate because my code
doesn't restore the ppgtt page directory correctly in the thaw function.
Patch:
http://cgit.freedesktop.org/~danvet/drm-intel/commit/?h=drm-intel-fixes&id=55a254ac63a3ac1867d1501030e7fba69c7d4aeb
Please test whether this fixes your issue. You can also try adding
i915.i915_enable_ppgtt=0 to your kernel cmdline.
Thanks, Daniel

Woot, I'm off the hook ;-) Thanks for reporting this issue and testing the
patch.

My guess is on the firmware load vs. suspend/resume fix that landed in
-rc2. That one fixed resume on all the machines here, and -rc1 broke
it on a lot of them.
