Hi folks -
Current wireless-dev, iwl3945 associated on WPA network okay
# echo -n "mon0" > /sys/class/ieee80211/phy0/add_iface
interrupts the association to the AP:
wlan0: associated
wlan0: switched to short barker preamble (BSSID=00:11:50:ad:ce:38)
(stable like this until mon0 created...)
PM: Adding info for No Bus:mon0

... (more of these "unknown keyidx")
association is re-established after some time by wpa_supplicant, but the
break in association seems to be specifically caused by adding the
virtual interface.
