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.

Likely a known regression, ppgtt support broke hibernate because my code doesn't restore the ppgtt page directory correctly in the thaw function.

Please test whether this fixes your issue. You can also try adding i915.i915_enable_ppgtt=0 to your kernel cmdline.
Thanks, Daniel
