Bug Description
Binary package hint: linux-image
System: Xubuntu 8.10, x86-64 generic/desktop
Hardware: Core2 Duo (Lenovo Thinkpad T400, US model 2764-CTO)
Kernel: 2.6.27 (-9, -10, -11)
When rebooting or shutting down, I consistently get the following crash dump (like kernel oops?) when the shutdown sequence reaches /etc/rc0.

The first few lines of the crash dump are like this:
iwlagn: Error: response NULL in 'REPLY_ADD_STA'
BUG: unable to handle kernel paging request at ffff8800ffff8880
IP: [<ffffffff80501

What's strange is this: I have been in contact with another T400 owner (UK model) and he also installed xubuntu 8.10 64-bit on his and he did not have this kind of problem. Does anybody else experience the same kind of problem?
After the crash above, the reboot/shutdown would not continue. Often I have to hold the power button to make it turn off.
Some workarounds:
* rmmod iwlagn before rebooting/shutting down -- then there is no such issue
* or, disable the wireless with the hardware button -- then the shutdown/restart went smoothly

I have the same issue with 9.04 Beta on a Dell XPS M1530.
