Can I have some volunteers please... Sam reports a panic when detaching a card on the fly with the IGMPv3 code. Whilst I've taken a few precautions in the netisr against this, most likely there is something getting used-after-free in the domifdetach ping-pong which I've missed in the rush. So to track this down, I really need a backtrace with full debugging symbols. I would encourage anyone who may face a similar issue to try to reproduce it with HEAD and send me a full backtrace. I may not get around to fixing this right away -- already on other stuff -- but will try to as time arises. Many thanks, BMS
