The issue happens somewhere between v3.18 and v3.19-rc1 in the mainline kernel repo. 
That's a ~11 step bisect, which will take some time on my laptop. I'll see if I can get this done at some point.

Title:
  [LENOVO 80H8] hibernate/resume failure

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I can't resume from hibernation, as the system seems to stall after
  PM: Image loading is done, and non-boot CPUs are disabled.

  The problem appeared after I upgraded from 14.04 to 15.04. I see from
  the apport-summary that there is a problem with PulseAudio - could it
  be the cause?

  
  I've attached a picture of what my screen shows before I have to do a hard reboot. Sorry about the quality of the picture.
