>Description:
	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.

State-Changed-Why:  
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.
