2). Suspend / Resume

3). Xorg CPU usage spikes over 70% now while scrolling in a browser

4). Playing a video slows system down completely

Ok, whatever new changes were added to Lucid proposed kernel, 2.6.32-26-generic, which I'm testing on Maverick, has the issue present again. This is 100 % reproducible after one suspend/resume.

https://launchpad.net/ubuntu/+source/linux/2.6.32-26.46

Prior to this proposed-kernel, this issue was non-existent on Lucid as well.

I have the same problem with 2.6.37-7 (natty).

I will have Xorg spike at 17% or 50% or more of CPU when moving mouse. There I just hit 34%. And 37%.

Only reliable way to fix is to reboot.

I only have pidgin and chromium (daily) running.

James Schriver, 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? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command in the development release from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. As well, please comment on which kernel version specifically you tested.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream', and comment as to why specifically you were unable to test it.

Please let us know your results. Thanks in advance.
