Interesting, so your RSTDBYCTL is the same and you're still in RC6.  So
something else in the cleanup patch is causing trouble.

Francesco, if you revert d5bb081b027b520f9e59b4fb8faea83a136ec15e do
both the hangs at X startup and suspend/resume go away?

Gui, same question for you.  And can you try this patch and dump
the contents of /sys/kernel/debug/dri/0/i915_drpc_info as well?  Your
settings are probably the same but I want to double check.

Thanks,
