Wifi: TL-WN821N could not read ROM / kernel page fault
TP-Link (TLWN812N 300Mbps) USB device. What I found really surprising
was that unplugging the device locked up the OS.
Due to message:

Sep 7 15:19:08 geeky /bsd: athn0: could not load firmware
I downloaded athn-firmware-1.1.tgz and extracted those files into
/etc/firmware. That file contained:
firmware/athn-ar7010
firmware/athn-ar7010-11
firmware/athn-ar9271
That led to the following when plugged in:

You in X-Windows, I assume.
I did try setting sysctl ddb.console=1 before unplugging the device again
but:
sysctl: ddb.console: Operation not permitted
You can't change that setting at run time. You need to set it in your
/etc/sysctl.conf file and reboot the system.
I'm not sure how else I can get a trace, ps, show registers, etc...
Try your experiment either from the console or set up a serial console
for the machine.

No, console. Usually a headless device running as a firewall.

Made change to /etc/sysctl.conf and rebooted with wireless device
connected. When login prompt appeared I unplugged the device and
nothing has changed.
I notice that once the lock up occurs, pressing the caps lock key no
longer lights the indicator light on the keyboard. There is a COM port
on this computer but it has a USB interface...

It's a package, like the manpage says, use pkg_add. # pkg_add http://firmware.openbsd.org/firmware/athn-firmware-1.1.tgz Maybe, but i doubt that this will resolve your problem. I removed the firmware files and ran pkg_add with the URL you provided. No change with the problem I'm having.
