The rfkill subsystem doesn't like code like that rfkill_allocate(); rfkill_register(); rfkill_unregister(); rfkill_register(); /* <- This will crash */ This sequence happens with modprobe b43 ifconfig wlanX up ifconfig wlanX down ifconfig wlanX up Fix this by always re-allocating the rfkill stuff before register.
