Bug Description

Some background:
 I've had wireless issues with this card from Feisty, Gutsy, and Intrepid due to the default NetworkManager not being able to use the card drivers. This was resolved in Jaunty by replacing NetworkManager with wicd and everything worked perfectly for months.

Following the upgrade to Karmic things have been usable but every 30 minutes to few hours the networking goes offline and the entire laptop locks up. This is only resolved by unplugging the card, waiting for the system to swap some unknown things in and out, then plugging back in again. After the resurrection syslog reliably contains "BUG: soft lockup" then usually the currently running app with most memory usage.

Attached is a trace from syslog at the second from one such event.

Linux troja. 2.6.31-16-generic #53-Ubuntu SMP Tue Dec 8 04:01:29 UTC 2009 i686 GNU/Linux
(happened in all kernels since 2.6.31-11)

Hi Amos,

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 495278

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.

I'm stuck with karmic for now unfortunately. I have kept up with the karmic updates hoping this would disappear at some point.
But yes it's still occuring several times a day (with the latest karmic kernel). Will try the mainline.

FWIW; this bug has not been occuring in any of the more recent updates of karmic kernels since my last post. (I was not able to test the mainline).

Accepting the closing. Maybe with a tentative "fixed" if you like.
