That sounds like it can be the same symptoms as I described on the
freebsd-mobile list earlier this week:

http://lists.freebsd.org/pipermail/freebsd-mobile/2009-February/011343.html

What clockrate do you run at?  On my system (Thinkpad X40, Atheros
5212) the problem does not occur at kern.hz=1000, but it is present at
kern.hz=100.

Tomorrow evening I will investigate this further including testing if
"ifconfig ath0 -bgscan" makes a difference for me.
