--- Comment #3 from Andriy Voskoboinyk <avos at freebsd.org> ---
r298925 may help with initial DOWN->UP->DOWN transitions; however

> May  2 11:50:51  kernel: wlan0: scan_curchan_task: loop start; scandone=0
> May  2 11:50:51  kernel: wlan0: scan_curchan_task: chan  11n ->   1g [active, dwell min 20ms max 200ms]
> May  2 11:50:51  kernel: wlan0: scan_curchan_task: waiting
(hangs here)

looks like a driver misconfiguration; for now,
https://reviews.freebsd.org/D6176 may workaround this issue (until more proper
fix will be found).
