I can confirm this on Lucid. Here is a extract of /var/log/kern.log

Bug description:
I've had repeated trouble with ath9k causing my system to lock up.  It's a macbook, late 2006 model, running 8.10.

lspci -v shows the following info:

Symptoms are the wireless network fails to respond and I am unable to reconnect.  I get repeated popups asking for WPA2 password, and lots of messages like this in the log:

[72782.981155] ath9k_config: Unable to set channel

First time this happens, I can clear the problem by unloading and reloading the ath9k module.  It will occur again shortly afterward.  Second or third time around the ath9k module will unload and reload fine, but following this any process that tries accessing the device will hang (NetworkManager, 'ifconfig', etc.) and the system becomes more and more unresponsive until I have to power off.

This bug is a showstopper for me and rebooting twice daily has shot my workflow to bits, so I'm happy to help debug this in any way I can.
