Oops when shutting down laptop

[Kristian Grønfeldt Sørensen <kriller@vkr.dk>]

Hi.

My laptop oops'es in the final phase of shutdown. It started this
Monday. I don't remember having done anything particular with respect to
the kernel around that time. It only happens when going to runlevel 0 -
a reboot does not result in an oops.

Until yesterday i used kernel 2.6.13-rc3, but i have now compiled
2.6.13-rc5 with some debugging support. However the problem persists.

Since the oops happens so late in the shutdown-sequence, that all
filesystems has been unmounted, i am unable to capture the oops on the
disc, but a picture of the oops is available at
http://www.vkr.dk/~kriller/oops.jpg . (Sorry for not writing the oops in
this mail).

I tried to remove all modules except speedstep_centrino, freqtable,
processor and ipv6 (reported as being in use),  before calling poweroff,
but with no change.

I'm not subscribed to the list - Please CC' me.

regards 
Kristian Sørensen
