>Description:
System drops to ddb at random intervals after upgrading to latest

This seems to be related to 11n changes.
I got following from ddb:

ddb{0}> show panic
the kernel did not panic
>How-To-Repeat:
Run system with athn in hostap mode.
Also seems to trigger when manually setting mode to 11g.
>Fix:
Unplug athn from system.
