Jithin Emmanuel, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please confirm this issue exists with the latest
development release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains,
could you please run the following command from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux REPLACE-WITH-BUG-NUMBER

If reproducible, could you please provide the information following
https://wiki.ubuntu.com/DebuggingKernelSuspend ?

If reproducible, could you also please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.3.13-rc7

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

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

Status in “linux” package in Ubuntu:
  Incomplete

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.

  Tasks: 198 total,   2 running, 195 sleeping,   0 stopped,   1 zombie
