Bug Description

This kernel panic has occurred a number of times, usually when I am watching a flash video (i.e. on YouTube). There have also been a number of incidences where the entire WM is locked up (cannot move mouse, cannot switch to console via ctrl-alt-F1) that occurs while watching flash videos, but I am unsure if those freezes are also KP's. I am including a photo of the kernel panic. I am new to reporting such bugs, and some pointers to where I can find this kernel dump would be useful, and I will include those logs if not included already.

This is happening to me since Natty, but only when I boot up my computer. Normally, after the second try it seems to boot fine though.

David Z. Chen, thank you for reporting this bug 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? 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.
