ath driver panics on 6-STABLE (LOR)

I bought two atheros based card: a dlink DWL-G520 pci for my home
router (via c3) and a DWL-G650 pccard for my laptop. I use it with my
Netgear 802.11g Access Point.

I'm having repeatedly panics, which I can't reproduce (if not waiting
a few minutes or some hours of activity), especially on the
router. I've upgraded to the latest RELENG_6 yesterday from 6-BETA
without success. Finally built kernel with debug symbols. Here's the
backtrace:

sberta:/home/satu/debug> kgdb -d crash/ -n 0 kernel.debug

Let me know what further information I may provide.
