I've tried to revert it and it hangs the same on the suspend/resume, so
I've setted inittab to work only in tty mode, and bisected the
suspend/resume problem from -rc4.
The bad commit is another:

drm/i915: re-enable rc6 support for Ironlake+
Re-enable rc6 support on Ironlake for power savings. Adds a debugfs
file to check current RC state, adds a missing workaround for Ironlake
MI_SET_CONTEXT instructions, and renames MCHBAR_RENDER_STANDBY to
RSTDBYCTL to match the docs.
Keep RC6 and the power context disabled on pre-ILK. It only seems to
hang and doesn't save any power.

I've tried to rever it on top of -rc4 to check if the suspend/resume
works, but it doesn't revert clean, and now I don't have the time to
check.
If you need some more information just let me know, anyway this seems
another unrelated problem.
Bye
Francesco
