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: commit 88271da3f3da75d6eaef5e768c82a1627edf7088 Author: Jesse Barnes Date: Wed Jan 5 12:01:24 2011 -0800 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. Signed-off-by: Jesse Barnes Signed-off-by: Chris Wilson 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
