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

[Bill Allaire]

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:

When unplugged:

Stopped at   ieee80211_ifdetach+0x3e: movl %edx,0(%eax)

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.

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



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.


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.

Re: pf ftp-proxy forward AND reverse (Help?)

Hi folks.
I cannot get reverse? ftp to work from my wireless to my LAN.
I seem to have no trouble going from the LAN to the internet.
Any thoughts?




Thanks,

I have the outgoing ftp-proxy listening on the default port.  I have the 
incoming ftp-proxy listening on a different port.  I also have only one 
anchor for ftp-proxy.
