Public bug reported:
Binary package hint: linux-image-2.6.17-11-generic
I clicked a mouse button, the machine froze, and I noticed this in
/var/log/kern.log upon reboot. I hope it will prove useful. The
machine was otherwise quiescent (and this is the only Oops visible in
its log). I recently upgraded to edgy and it has seemed stable for
several days.
