Title:
  Ubuntu fails to Shutdown or Restart

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  I have a Dell Studio 1569 and I am running Ubuntu 12.04.1 LTS. When I
  attempt to shutdown my laptop, everything seems to go fine until "Will
  now Halt." (in the case of shutting down) or "Will now restart." (in
  the case of restarting).  The system just hangs at this point and does
  not power off.  If you wait approximately 22s, the kernel starts
  complaining about a soft lockup. I have tried shutting down from the
  menu, terminal, as root, etc and even changing runlevels to initiate a
  shutdown.
