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. Bengt
