>Description:
There is a problem (incompatibility bug ?) when kernel is compiled with device vlan and device gif.

When you create the gif interface with the command "ifconfig gif1 create" after the creation of a vlan interface, the machine freeze.
Please note that if you create the gif interface before the vlan interface it's work.
>How-To-Repeat:
ifconfig vlan1 create
ifconfig vlan1 inet 192.168.0.1 netmask 255.255.255.0 vlan 3 vlandev ti0
ifconfig gif1 create

Machine freeze after the command "ifconfig gif1 create".

>Fix:
Compile kernel without device vlan. When device vlan is needed, it will loaded as module.
