Ugh. I was hoping that we'd get more reports on this, right now
there's not enough information to even make a guess about what's up.

I also note that no actual i915 people were cc'd, despite your
graphics driver suspect. Adding Daniel and Dave (one of the millions)
to the cc since they probably do have lkml but probably don't react
unless something gets pointed out.

Daniel/Dave, do you have any reports of hibernation failing (or VT
switching problems) with i915 after 3.6?

Rafael, do you have logs of the suspicious RCU usage etc reports?
