Title:
  Computer freezes on hibernate

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Since version 4.2.0-35 hibernation fails when there's significant RAM
  usage, like running google chrome with tens of open tabs. The screen
  will turn dark, display goes to sleep mode, but the computer just
  hangs and doesn't power off. (I am still able to ping the machine, but
  can't ssh in for example). When I reset the machine, it will just boot
  normally instead of resuming. The problem doesn't show when there's
  low RAM usage (like, just hibernating from an empty desktop) and it
  doesn't show when running 4.2.0-34.
