Bug Description

I'm not sure what happened, I hope the stack trace will make sense. I updated to Natty last night, and I was working on battery for the first time today. I worked on wifi before, the system didn't crash for a few hours. I've been on battery for ~30 minutes. I got 2 more crash notices while filling out this report, so I think the bug will show up in a consistent manner.

Victor Costan, 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, please answer the following questions:
+ Is this still reproducible?
+ What impact does this have on your using your computer?
+ 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.
