I just upgraded a laptop to FreeBSD RELENG_7 checked out on 20071016.
Previously, iwi0 had worked OK under FreeBSD 6.2. After updating to 7,
though, iwi0 reports "firmware error" and nothing more happens. I have
set legal.intel_iwi.license_ack=1 in /boot/loader.conf. wpa_supplicant
and dhclient are running with the same configurations that worked under
FreeBSD 6. I'm using the GENERIC kernel with SCHED_ULE instead of
SCHED_4BSD, and the loaded modules are:

I've tried setting debug.iwi=1, and the kernel messages regarding iwi0
are:

Any ideas?

Me too.
(It works in authmode OPEN though, see my case on
http://lists.freebsd.org/pipermail/freebsd-current/2007-August/076397.ht
ml)

On my notebook, I get similar errors most of the time. The problems
started some months ago.

If I don't configure iwi0 via /etc/rc.conf, I can get WPA working
something like this:

ifconfig iwi0 up
wpa_supplicant -d -i iwi0 -c /etc/wpa_supplicant.conf
dhclient iwi0

IIRC it worked most of the time via /etc/rc.conf if I disabled
WITNESS/INVARIANTS. Haven't been using the notebook too much lately, so
I'm not sure if this is still true.

I just tested this on a t42 w/ 2200 card and it worked for me. Try
setting debug.iwi to something like 2 or 5 and collect a log. The
firmware is very finnicky and getting it to integrate w/ wpa_supplicant
was a challenge.

I upgraded to a fresh CURRENT.

Most of the time it works during startup. I couldn't reproduce the firmware
error message with debug.iwi enabled.

What used to work and now causes the firmware error message is when I
kldunload if_iwi. This used to work some time ago, e.g. iwi was automatically
reloaded and successfully associated. (I use this for suspend/resume)

I only get wpa_supplicant to work again if I do ifconfig iwi down/up.

Here's the log
http://stud4.tuwien.ac.at/~e0125637/fbsd/iwi.log

My laptop (Acer TravelMate 4102) has this problem, too.
The workaround is:
1. Turn off radio switch.
2. sudo kldunload if_iwi
3. Goto 2. if console printed "firmware error."
4. Trun on radio switch.
5. Wi-Fi is workable now.
