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 tonight. 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. -- Jille
