Hi,

Thanks for that. Hm. The problem is still not clear. There's no state
transition, so I guess it's going into scan mode and out of scan mode
again.

How about doing this:

wlandebug +state +power
sysctl dev.ath.X.debug=0x00040000

That enables the _driver_ state checking. That should log when
ath_scan_start and ath_scan_end are called.

This is definitely a tricky one..
