A bad wlan setup in a hotel forced me to restrict the wlan-mode to use 802.11b only - under windows xp. That is why I tried to set mode to 11b under FreeBSD (same hardware) because I experienced the same network problems as with XP.

Hardware used is HP Laptop Compaq nx8220 with Intel(R) PRO/Wireless 2200BG.

% ifconfig iwi0 mode 11b
Sleeping thread (tid 100085, pid 1227) owns a non-sleepable lock
panig: sleeping thread

This happenes on 6.1-RELEASE-p6 with iwi-firmware-2.4_7 and might be related to older kern/89926 or kern/87413.
buy a compaq nx8220 laptop, install freebsd 6.1, update to 6.1-RELEASE-p6, install iwi-firmware-2.4_7 and type "ifconfig ini0 mode 11b" as root.
