Public bug reported:
1) Enable the rtap_iface of the ipw2200 driver by echoing 1 in
/sys/module/ipw2200/drivers/pci:ipw2200/*/rtap_iface
2) ifconfig rtap0 up
3) Use the eth1 wireless interface (eg. send some data, connect to a
network) or even just run ifconfig many times
4) A kernel panic occurs.
I'm attaching two screenshots of the panic, took one on 3.0.0-16-generic
and one on 3.0.0-16-generic-tuxonice.
uname -a is:
Linux VittGamLaptop2 3.0.0-16-generic-tuxonice #29~ppa1-Ubuntu SMP Fri Mar 9
10:57:58 UTC 2012 i686 i686 i386 GNU/Linux
The computer is an IBM Thinkpad X41.
