	I have a Kernel with pf + pflog + pfsync + carp.
        Build a double carp-environment:
	    carp0: flags=41<UP,RUNNING> mtu 1500
		    inet netmask 0xffffffe0 
		    carp: MASTER vhid 1 advbase 1 advskew 0
	    carp1: flags=41<UP,RUNNING> mtu 1500
		    inet netmask 0xfffffc00 
		    carp: MASTER vhid 2 advbase 1 advskew 0

	If I change the vhid to 1 for carp1, the kernel crashes 
	... hit key or restart in 15 sec.

	ifconfig carp1 vhid 1
	Dont do?
