Tested on a fresh install of 5.2.1-RELEASE (straight off the CD) and it works also.

>Description:
	Complete hanging of box after preforming the ifconfig rain-dance.
	ifconfig -C producing wierd results just before the last command.
>How-To-Repeat:
	As root:
	
	ifconfig -C
			Output: lo ppp faith gif
	ifconfig ppp0 create
	ifconfig ppp0 destroy
	ifconfig -C
			Output: ppp lo ppp lo ppp
	ifconfig gif0 create
	
	I suspect the ifconfig -C lines can be left out, but it shows interesting results, and thats how i caused it each time, so they were left in.
	After you run 'ifconfig gif0 create' the box will hang.

>Fix:

	Unknown
