I have the same problem if I load it with kernel modules.
If I compile it into my kernel (with ath, ath_hal and that option (can't
remember it for now)) my system paniced during boot.
I can't get a coredump, but I will try getting a stacktrace with ddb
My Atheros (2413 iirc) wasn't usable before the import (did some
printf's during boot, but I couldn't get ath0 showing up in ifconfig)
I am willing to help debugging if needed.
