Description Christian Wittenhorst 2003-07-09 08:40:00 UTC 
	Fatal trap 12: page fault while in kernel mode
	fault virtual address      = 0x2c
	fault code                 = supervisor read, page not present
	instruction pointer        = 0x8:0xc0338384
	stack pointer              = 0x10:0xc86448b4
	frame pointer              = 0x10:0xc86448b8
	code segment               = base rx0, limit 0xfffff, type 0x1b
	                             DPL 0, pres 1, def 32, gran 1
	processor eflags           = interrupt enabled, resume, IOPL=0
	current process            = 12 (swi1:net)
	trap number                = 12
        panic: page fault

Fix: 

unknown
How-To-Repeat: 	ifconfig vlan0 create
	ifconfig vlan0 vlan 4 vlandev nge0
	<kernel panic here>
	ifconfig vlan0 inet 212.203.72.13 netmask 255.255.255.240

I get the same :

Some fix would be nice

# ifconfig vlan8  vlan 700 vlandev nge0
# ifconfig vlan8 up
