You have been subscribed to a public bug:

I'm trying to enable a reliable hibernate/resume cycle on a intel haswell cpu/gpu system with ubuntu 13.10 +xfce. Until now I've failed, because I get three possible outcomes, when resuming (without seeing any pattern). In all cases pm reports, that 'Image restored successfully'; visible on tty1.
Resulting system states after resume:
i) resume just works fine, everything is o.k
ii) X freezes, screen is completely black, mostly no reaction to key strokes (i.e. can't change to ttyX), but ssh is possible
iii) like ii) but network is not reachable (I'd say a complete freeze)

>From situation ii) I got a dmesg (attached), which makes me think, that
intel gpu driver is to blame.
