	I guess it could be because you use Intel Processors.
	The bug didn't show up on my P3 and P4 boxes, only on
	on athlon K7.

		-------------------

	I think I found another bug, that I can reproduce
	in a very "creative" way:

	Start the access-point on the Athlon with this 
	script:

ifdown ath0
ifconfig ath0 down
rmmod ath_pci
rmmod wlan
rmmod ath_hal
rmmod iptable_filter
rmmod ip_tables
sleep 2
iwconfig ath0 essid "mirofhome" mode Master rate 11M
sleep 3
ifup ath0
sleep 3
iwconfig ath0 essid "mirofhome" mode Master rate 11M
iwconfig ath0
ifconfig ath0

	Start another PC (D-Link G650 on a PIII laptop),
	and run a ping <IP-of-AP>

Re-run the script on the AP.

	This crashes the AP about 40% of the time.
	If it does not crash, re-run the script
	until a crash. (while keeping the ping
	running)

	This reproduces the oops quite consistenty.

	I'm tracing this down, I have a couple of
	oopses to work with. The culprit is somewere in
	wlan.c, but I don't understand exactly
	where.
