>Description:
If you try to configure a bridge based on vlan interfaces during the boot process, the startup scripts are failing because the vlan interfaces are created after the bridge interface.
>How-To-Repeat:
one example:

/etc/ifconfig.vlan31:
create
vlan 31 vlanif ixg0

/etc/ifconfig.vlan103:
create
vlan 103 vlanif ixg0

/etc/ifconfig.bridge0
create
!brconfig $int add vlan31 add vlan103


the startup scripts try to create the bridge interface before the vlan interfaces are ready
