Title:
  Hard hang on resume from suspend

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Every so often, I will suspend my laptop and get a hard hang with a
  blank screen when I resume.  Last time but one Alt-Sysrq-C worked
  (judging by the flashing keyboard LEDs), last time (a few minutes ago)
  it didn't.  So far I have failed to get any information on the hang.
  I tried installing a crash kernel, but it hasn't got me a crash dump
  yet (though I was able to trigger one manually), and needless to say
  there is nothing in the system log.

  There is a chance that this is related to VirtualBox, as I have the
  current development code running on this system.  At the moment I
  would most appreciate clues as to how to debug this (unfortunately
  netconsole isn't really an option as it happens so unpredictably, and
  most often when I don't have a second system available anyway).
