Wifi: TL-WN821N could not read ROM / kernel page fault

Bill Allaire-3
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 at uhub0
Sep  7 15:19:08 geeky /bsd:  port 1 "ATHEROS UB95" rev 2.00/2.02 addr 3
Sep  7 15:19:08 geeky /bsd: athn0: failed loadfirmware of file
athn-ar7010-11 (error 2)
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:

Sep 11 10:30:05 geeky /bsd:  port 1 "ATHEROS UB95" rev 2.00/2.02 addr 3
Sep 11 10:30:07 geeky /bsd: athn0: bad ROM checksum 0x2c17
Sep 11 10:30:07 geeky /bsd: athn0: could not read ROM
Sep 11 10:30:07 geeky /bsd: athn0: could not attach chip


When unplugged:

uvm_fault(0xd0a31aa0, 0x0, 0, 3) -> e
kernel: page fault trap, code=0
Stopped at       ieee80211_ifdetach+0x3e:     movl     %edx,0(%eax)
ddb{1}> (lost keyboard response at this point)

I did try setting "sysctl ddb.console=1" before unplugging the device
again but:
sysctl: ddb.console: Operation not permitted

I'm not sure how else I can get a trace, ps, show registers, etc...

You in X-Windows, I assume.

You can't change that setting at run time. You need to set it in your
/etc/sysctl.conf file and reboot the system.

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...

I removed the firmware files and ran pkg_add with the URL you provided.  
No change with the problem I'm having.

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 at uhub0
Sep  7 15:19:08 geeky /bsd:  port 1 "ATHEROS UB95" rev 2.00/2.02 addr 3
Sep  7 15:19:08 geeky /bsd: athn0: failed loadfirmware of file
athn-ar7010-11 (error 2)
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:

Sep 11 10:30:05 geeky /bsd:  port 1 "ATHEROS UB95" rev 2.00/2.02 addr 3
Sep 11 10:30:07 geeky /bsd: athn0: bad ROM checksum 0x2c17
Sep 11 10:30:07 geeky /bsd: athn0: could not read ROM
Sep 11 10:30:07 geeky /bsd: athn0: could not attach chip
Did you manage to find a solution to your problem? I am having the same device, and I am getting almost the same error as you:

dmesg | grep athn

athn0 at uhub0 port 1 "ATHEROS USB WLAN" rev 2.00/2.02 addr 2
athn0: bad ROM checksum 0x2c64
athn0: could not read ROM
athn0: could not attach chip

In case you manage to solve it, you might want to share the golden bits?  (-;
