Title:
  [karmic kubuntu] high cpu usage after suspend to ram

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Not sure if this needs to be applied against firefox or xserver.Please
  change if needed.

  After I did a sleep(suspend to ram) My applications kmail,firefox-3.5,
  ktorrent and xorg was consuming high cpu usage with xorg and firefox
  leading the pack. After around 15 mins. It stabilised and cpu usage of
  all processes returned to normal , like before I did sleep.

  But even after that when ever I use firefox-3.5 (like normal browsing)
  there is a spike in cpu usage.

  top output during the time.
