* Correct system hangs when resuming from hibernation after
  first successful hibernation/resume cycle.
  * Rare condition involving OFA.

Note: suspend/resume is not supported on many platforms.
      It was originally intended for workstations. This patch
      is already in our out-of-box driver and has undergone a
      lot of testing.
