Title:
  [Dell Precision M6600] Suspend puts laptop in state requiring hard
  power down + power up

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  At random (I estimate perhaps 20-25% of the time), when I suspend my
  Kubuntu 14.04 (upgraded from 13.10, not a fresh install) laptop, it
  blanks the screen, and displays a message such as that below on the
  text console.  Then, instead of going to sleep, it remains powered up.
  In this state, nothing works to get back control, not Ctrl-Alt-Del,
  Ctrl-Alt-Backspace, Ctrl-Alt-F2 (or other function key), not ^C.  The
  only way I have found to get control is to hold the power button down,
  which is a power-down and then power-up.

  Message on console is:
