kernel panics when i do 'iwconfig' after configuring and starting wlan0

[qrto]

Steps to reproduce:
iwconfig wlan0 mode ad-hoc
iwconfig wlan0 channel 10
iwconfig wlan0 essid "Penguin"
iwconfig wlan0 enc on
iwconfig wlan0 key s:*****************
ifconfig wlan0 192.168.0.11 up
route add default gw 192.168.0.1

after that wireless works (connects) but typing: iwconfig = kernel panic

If i do above in graph enviroment it automatically does kernel panic (probably because some applet uses iwconfig in the background).

This oops was occuring with a very old Karmic alpha kernel 2.6.30-9, could you confirm whether this is occuring with the latest karmic kernel 2.6.31-10.32 or later. Please report back here. Thanks!

I'm using 2.6.31-10 now, and everything works perfect :)
