Comment 1 Josh Boyer 2012-04-10 00:27:45 UTC

Was this resumed after a hibernate?

Comment 2 Peter 2012-04-10 00:56:04 UTC

Well, yes. 2.5 hours of work + video after resuming from hibernation. Kernel crashed the very moment I pressed <enter> after typing "find / -name <something>"

OK.  There is a known i915 hibernate corruption bug that hits in the 3.x series.  It's fixed in the latest 3.3.1-3 update for F16.  Probably worth testing to see if that helps your issue.
