Public bug reported:
Even though I no longer get kernel panics from iwlagn, the bugs are
still not completely fixed.
Hardware: HP Compaq 8710W, Core 2 Duo T7700 @ 2.40, 2gb ram, Mobile

Kernel: Linux oc-laptop 2.6.28-7-generic #20-Ubuntu SMP Mon Feb 9 15:42:34 UTC
2009 x86_64 GNU/Linux
OS: Ubuntu Intrepid and
Description: Ubuntu jaunty (development branch)
Release: 9.04
Wireless is disabled, and modprobe -r && modprobe, nor rmmod or insmod
will reload the iwlagn (nor cfg80211, iwlcore, mac80211, ...) module.
Once in a while I get the following traces in my messages. A reboot is
required to get wireless up and working again.
