This seems to be somewhat related to suspend and I once again got what looks like the same oops after doing a suspend and resume cycle. This cycle was unusual in that after opening the lid of the laptop it resumed and then immediately suspended again. I've attached the full kern.log up to the time of the oops.

Thank you for taking the time to report this bug and helping to make Ubuntu better. This particular bug has already been reported and is a duplicate of bug 528753, so it is being marked as such. Please look at the other bug report to see if there is any missing information that you can provide, or to see if there is a workaround for the bug. Additionally, any further discussion regarding the bug should occur in the other report. Please continue to report any other bugs you may find.

It's interesting that this bug is marked as a duplicate of a bug reported an hour ago, when this was reported back in November of last year. I guess either way is fine.

[Anzenketh (anzenketh)]

Reason for that Is I felt the other bug contained a better description of the issue. The master bug is based on the best description not the oldest.

[Pedro Côrte-Real (pedrocr)]

Makes sense. The description does shed some light on what is happening. I was also using skype. I did use apport though. Any of that info helps?

Watch the main bug and respond to any requests to get more info.
