After this morning's update of head from:

FreeBSD g1-55.catwhisker.org 13.0-ALPHA1 FreeBSD 13.0-ALPHA1 #124 main-c256=
006-g8ca9ff4f28d2-dirty: Sat Jan 16 05:47:48 PST 2021     root@g1-55.catwhi=
sker.org:/common/S4/obj/usr/src/amd64.amd64/sys/CANARY  amd64 1300135 13001=
35


to:

FreeBSD g1-55.catwhisker.org 13.0-ALPHA1 FreeBSD 13.0-ALPHA1 #125 main-c256=
026-gb7ab6832cd98-dirty: Sun Jan 17 04:49:26 PST 2021     root@g1-55.catwhi=
sker.org:/common/S4/obj/usr/src/amd64.amd64/sys/CANARY  amd64 1300135 13001=

on my laptop, the wireless link failed to associate by the time the
xdm login screen came up.  But when I logged in (on vty1) and issued:

	service netif restart wlan0

it associated right away.  (There was no issue with the corresponding
update for stable/12, so I have no reason to believe that there is an
issue with the access point or the laptop -- with respect to associating
properly, at least).  And whether in head or stable/12, the woreless
link has (for the past several months of daily tracking both head and
stable/12) almost always associated by the time the xdm login screen
comes up.

I tried it 3 times; each time, it failed to associate.  (I only tried
the "service netif restart wlan0" the last 2 times -- the first time,
vty1 wasn't usable because I had experimented with a /boot/loader.conf
setting, which (as far as I know) is not relevant to this issue.)

Peace,
david

Mr. Trump: We did not need you to demonstrate the efficacy of the "big
lie" propaganda technique quite so well -- really.  Please stop.
