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.

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.
