Title:
  Dell Latitude E7240: Random hang on suspend

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu Trusty / 3.13.0-30-generic #55-Ubuntu

  When suspending a Dell Latitude E7240 by closing the lid, most of the
  time it will suspend fine. Sometimes it doesn't. When it doesn't, the
  screen will remain on and will display the lock screen, but mouse
  keyboard clock etc are completely frozen. Attaching a crash log from a
  representative example.

  This occurs somewhere between one suspend in every ten to one suspend in every two. Occurs on both battery and AC power.
