Well, I see the same on FreeBSD/MIPS whenever an Atheros device is
fondled incorrectly. Either because the chip isn't yet fully awake or
the register plainly doesn't exist.

See if you can add some debugging in ath5k_hw_reset_tx_queue() to see
which register is being read/written before the PCI bus error occurs.

I have that hardware (routerstation/rspro) and the CM-9 card but I
don't currently have any spare time to run it up and test, sorry.

Recently trying to abandon madwifi for good on some embedded devices
with OpenWrt, encountered kernel panics.  Same radio on an x86
platform (Soekris net4826), no kernel panic.  Different atheros radio,
no kernel panic.  Tried two different MIPS boards (Netgear WGT634U and
Ubiquiti RouterStation), both panic'd.

Netgear WGT634U:  http://pastebin.ca/2051127
Ubiquiti RouterStation: http://pastebin.ca/2052610

Both cases were firmwares built from r26771 of OpenWrt, and both seem
to have panic'd from hostapd.  While researching this, I encountered a
similar report from last June:

Another person reported some issues with the CM9 earlier this year in
client mode:

I am happy to do some leg work on getting this fixed, if someone can
provide some guidance.  Thanks!
