Description pcasidy 2001-04-11 21:30:00 UTC 
	If one insert an unsupported modem PCCARD such as 3COM 3056 with
	good entries in pccard.conf, the kernel freeze and the only
	solution is to hard reset the computer.
	There is a while(TRUE) at line 1469 of isa/sio.c
	$FreeBSD: src/sys/isa/sio.c,v 1.291.2.16 2001/03/12 13:47:29 sanpei Exp $
	which is not interruptable. That freezes the kernel if the device is
	not recognized.

How-To-Repeat: 	Modify the pccard.conf to recognize an unsupported sio card.
	Insert the card with pccardd running.

Wont fix.  It isn't sio's job to guard against things like this.  I 
also don't have a card and can't test it effectively.
