Bug Description

The Natty 2.6.38-8-generic kernel oopses about once a day on my Thinkpad R500 in x86_64 bit mode. Maverick was very stable. I need the Natty kernel to get proper KMS for my Radeon graphics card.

I don't know if it's related, but it also does a controlled shutdown once a day as well - as if you ran 'sudo shutdown'.

Photo of the backtrace is attached.

I've been running linux-image-2.6.39-0-generic 2.6.39-0.5~20110427 from the PPA for a week now and it's fine so this is Ubuntu or 2.6.38 specific.

Michael Hope, thank you for reporting this and helping make Ubuntu better. 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 attach all information noted in https://wiki.ubuntu.com/Kernel/DebuggingSchedulingWhileAtomic ? As well, 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 <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 . 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.
