[Jim Lieb (lieb)]

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.

[Jim Lieb (lieb)]

This bug report is being closed because we received no response to the previous inquiry for information. Please reopen if this is still an issue in the current Ubuntu release, Karmic Koala 9.10. To reopen the bug, click on the current status, under the Status column, and change the status back to "New". Thanks.

[Kev Walke (kelvinelk)]

But the current release is Jaunty, not Karmic! There seems to be this attitude that problems will simply go away on update to the next version. This problem is reported on Jaunty against linux 2.6.28. Do we no longer get support for the current release? Come on, play fair. The original reporter has already supplied lots of information about this. If you need more information, or such, then please ask, but I will not be updating to a beta operating system on my production server.

[Kev Walke (kelvinelk)]

looks like this may be a duplicate of #347711 ?

[penalvch (penalvch)]

JaD! | Ferrer, 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 test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release 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>

Also, could you 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-v3.13-rc4

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.
