There are some changes in this code to better deal with this issue (network load on SMP systems) in 2.6.30. These changes are included in Karmic.

Can you also confirm this issue still exists with the most recent Karmic Koala 9.10 Alpha release? ISO CD images are available at http://cdimage.ubuntu.com/releases/karmic/ . If the issue remains with Karmic it would be great to then also test the latest upstream mainline kernel available. This will allow additional upstream developers to examine this issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Thanks in advance.

Hi kolen,

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 from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 407800

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 . 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. Please let us know your results.

Thanks in advance.
