Description:
The kernel crashes randomly because of an iwlwifi bug.
It seems to happen when using WPA and under high CPU usage.
Same problem with lots of different kernels, including 2.6.29.2-ARCH and 2.6.30-rc4.

Additional info:
* messages.log
* a developer reported this was fixed in compat-wireless
http://markmail.org/message/ggsqu5f6h54qynyj
after some research, I found this patch which probably fixes the bug (not tested yet)
http://git.kernel.org/?p=linux/kernel/git/iwlwifi/iwlwifi-2.6.git;a=commit;h=1a2b8d994b61a53338ffda1629ae3baaf690a9d8

Steps to reproduce:
* difficult to reproduce, see description
   iwlagn.log (2.9 KiB)

Maybe this is why my laptop crashes randomly without reason, bug report and log, when using wvdial with usb mobile modem on kernels 2.6.29 and 2.6.30

Here with wifi-link 5100 (WPA) and 2.6.30 and never had kernel panics for this module.
If there are some steps to reproduce the behavior I can help sorting it out.

i also can't reproduce this with .30 and iwlagn (5100)

I'm using the ARCH kernel now, no crashes (i686 and x86_64).
