  system becomes very slow after suspend/resume

Status in “linux” package in Ubuntu:

Bug description:
  My quad core i5 iMac becomes unusably slow after resuming from
  suspend.  One process will take 100% of a CPU (and nothing will run on
  the other cores).  This process is usually Xorg or beam.smp, although
  sometimes firefox or evolution will take over.  I have observed this
  with and without the ATI drivers.  Logging out and in does not fix the
  problem for more than a minute or so - only a reboot seems to clear
  the problem.
