	rtsol aue0 crashes the machine instantly.
	traceback is:

	rtsol aue0 on a IP enabled network.
	As far as I can tell, the usb framework called needs to be able to
	sleep. So the fix would be to create a kernel thread and defer
	setting multicast addresses to it. In netbsd-4 and later, 
	workqueue(9) seems to easiest to do - in which case, netbsd-3 would
	stay broken.
