Sorry, didn't remember that power-cycle was required. Where is that documented? 
Also, why (curious why a regular reset isn't enough)?

I asked systemd, and got the (rather generic, from my googling) answer:

root@beaglebone:/home/debian# systemctl status systemd-modules-load.service
● systemd-modules-load.service - Load Kernel Modules
   Loaded: loaded (/lib/systemd/system/systemd-modules-load.service; static)
   Active: failed (Result: exit-code) since Sat 2000-01-01 00:00:08 UTC; 15 
years 8 months ago
     Docs: man:systemd-modules-load.service(8)
           man:modules-load.d(5)
  Process: 162 ExecStart=/lib/systemd/systemd-modules-load (code=exited, 
status=1/FAILURE)
 Main PID: 162 (code=exited, status=1/FAILURE)

Warning: Journal has been rotated since unit was started. Log output is 
incomplete or unavailable.

I looked through the modules-load.d directories, and found only one that had 
anything in it:

root@beaglebone:/home/debian# ls /etc/modules-load.d
modules.conf  mt7601.conf
root@beaglebone:/home/debian# cat /etc/modules-load.d/modules.conf 
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

root@beaglebone:/home/debian# cat /etc/modules-load.d/mt7601.conf  
mt7601Usta

I do have a little MediaTek dongle plugged in, although I'm not sure how Linux 
magically installed a module conf file for it (this is the stock console, but I 
did do apt-get install wireless-tools, did that see the dongle and install it?).

Anyway, I'm still not sure what's actually failing, or if it's important. The 
board seems to be working, Ethernet certainly works, and iwlist scan returns 
APs in the area, so I think the wifi dongle came up okay.

Anyway, not too worried about it for now, just curious.

Thanks,
Rick
