Thank you for posting that information, William. I've made the usual
check on my workstation with every EL5 base kernel installed --

[ajb@stxsl ~]$ rpm -q kernel | sort
kernel-2.6.18-128.el5
kernel-2.6.18-164.el5
kernel-2.6.18-194.el5
kernel-2.6.18-53.el5
kernel-2.6.18-8.el5
kernel-2.6.18-92.el5
kernel-2.6.35-4.bcat
[ajb@stxsl ~]$ grep -i 168c /lib/modules/*/modules.alias | grep -i 002b
/lib/modules/2.6.18-194.el5/modules.alias:alias
pci:v0000168Cd0000002Bsv*sd*bc*sc*i* ath9k
/lib/modules/2.6.35-4.bcat/modules.alias:alias
pci:v0000168Cd0000002Bsv*sd*bc*sc*i* ath9k
[ajb@stxsl ~]$

This confirms that the ath9k has only been recently back-ported to the
EL5 kernel by Red Hat.

For testing purposes, to see if your issue is a result of the RH
back-port of the driver or if it is a result of hardware problems, you
could install the kernel-2.6.35-4.bcat [1]. If it does turn out to be
a driver issue, it should then be reported upstream at Red Hat's
bugtracker [2].

Alan.
