I can now reproduce it by hibernating two times. As the attached dmesg shows, resume after first std works fine, resume from the second std onwards results in no video output. As it may be a kernel issue, I tested it with the 3.11 saucy and the 3.12 tusty kernel. Both show the same behavior.

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.
