Title:
ath9k causes system lockup
Status in Mactel Support:
Fix Released
Status in “linux” package in Ubuntu:
Won't Fix
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:
02:00.0 Network controller: Atheros Communications Inc. AR5008 Wireless
Network Adapter (rev 01)

Capabilities: [100] Advanced Error Reporting <?>

Kernel driver in use: ath9k
Kernel modules: ath9k
Kernel:
Linux uviol 2.6.27-7-generic #1 SMP Fri Oct 24 06:40:41 UTC 2008 x86_64
GNU/Linux
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.
