It's not reproducable in a reliable fashion, but sometimes I get a hang during bootup shortly after ath0 is brought up. I also see an interupt storm on irq11, which I believe is also shared by ichsmb (at least on my Thinkpad T60p). If there is more information I can make available, I'm more than willing. I'd like to provide a defined way to cause this, but it doesn't seem to happen in a "regular" way. If anyone has suggestions on this, please share.
