I have a firmware problem with iwi(4) on recent current.
iwi0: <Intel(R) PRO/Wireless 2200BG>

It throws "iwi0: firmware error" if it has setup to associate in authmode WPA
(via wpa_supplicant). It worked for me before 80211n introduce.
Otherwise, it associates as well in authmode OPEN (without supplicant).
Any hopes it will be fixed before 7.0?

Also I can get "firmware error" if I kill watchdogd and then system goes to KDB
state over a specific timeout. Nevertheless, after 'continue' command
it associates
in OPEN, and not in WPA (i.e. same as mentioned above).
Cut from dmesg right after watchdogd's death:
