Public bug reported:
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.
