There is random corruption problem with hibernation on i915 (RHEL bug 746169, there is opened bug for fedora as well, but I don't remember where).

So do not hibernate, or if want use hibernate on that hardware use i915.modeset=0 kernel boot parameters.

Comment 2 Jason Scalia 2012-02-26 21:14:35 UTC

Thanks for the information Stanislaw. Was this the fedora bug you had mentioned https://bugzilla.redhat.com/show_bug.cgi?id=770754 ? If so, should we mark this as a dupe?

Thanks.

Comment 3 Stanislaw Gruszka 2012-02-27 07:56:59 UTC

Nope, 770754 is a RHEL bug. I'm closing this one as duplicate of already reported Fedora issue ...

*** This bug has been marked as a duplicate of bug 770754 ***

Err, 770754 is fedora bug, I'm dizzy with those numbers ... 

Anyway this bug is closed as proper duplicate.
