When unloading the ipw2200 module, then reloading it with option
rtap_iface=1, and activating rtap with ifconfig rtap0 up, NetworkManager
tries to reconnect to the wireless router. The kernel panics.
Walkthrough :
- modprobe -r ipw2200
- modprobe ipw2200 rtap_iface=1
- ifconfig rtap0 up
- wait
- Oops ...
The PC is an alienware Aurora m9700, the ipw card is an Intel PW ABG 2915, and
the router a Livebox pro (Inventel DWB-200)
Connexion is made via WPA-PSK/TKIP
Security concern as it could lead to a DoS via voluntary kernel crash.
