The attached files are not from the 11.04 upgrade, as that is
sufficiently unresponsive after the kernel oops that I had to reinstall
a copy of ubuntu 10.10 on the spare disk partition. So believe the
hardware portions but not the software.
This occurred immediately after the upgrade from ubuntu 10.10 --> ubuntu
11.04 beta 1 (amd64). A from-scratch install of ubuntu 11.04 beta 1 on
yet a third partition with the nouveau driver does not exhibit this
oops. Actually, it doesn't have this oops when the restricted nvidia
driver is installed either, but there is a different problem with that
I'll file another bug against.
The kernel backtrace as listed in /var/log/syslog is:
