I can't tell you exactly what happened or what caused it, but apparently it's a "serious kernel problem". I cannot recreate the steps that lead to this and as far as I can tell, the system has not been affected by this (other than the crash message that came up). This is the first bug I'm submitting, so hopefully that is useful!

Lorenz, thank you for reporting this and helping make Ubuntu better. Maverick reached EOL on April 2012.
Please see this document for currently supported Ubuntu releases:
https:/
We were wondering if this is still an issue in a supported release? If so, can you try with the latest development release of Ubuntu? ISO CD images are available from http://
If it remains an issue in a supported release, could you run the following command from a Terminal (Applications-
apport-collect -p linux <replace-
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:/
Thanks in advance.
