[Bug 1250498] Re: haswell, no video output after 2nd resume from suspend to disk (S4)


Same in single user mode, so I guess its a kernel issue.

  haswell, no video output after 2nd resume from suspend to disk (S4)

Status in “linux” package in Ubuntu:

Bug description:
  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.
