Subject: oops during reboot in device_shutdown()

Hi!

While running RIPLinux* 6.3, I got the below oops.

What I did was boot up riplinux from USB key, start X, the run "reboot -f" on VT2.

* - http://www.tux.org/pub/people/kent-robotti/looplinux/rip/

After the oops I run "reboot" again and got the same oops again.
Note: I am not sure if I ran the 32 or 64 bit kernel.

For kernel config and (3 smallish) patches see:
http://www.tux.org/pub/people/kent-robotti/looplinux/rip/docs/kernel.txt
(or http://www.tux.org/pub/people/kent-robotti/looplinux/rip/docs/kernel64.txt)


HW: Asus P5K-E WiFi maonboard, BIOS version 1013
(Intel P35/ICH9R), CPU: Intel Core2 Q6600

The oops (both):
