lagg interface not created at reboot ( 9.0 )

[Frank Bonnet]

hello

I use the lagg feature on a server and it seems the lagg pseudo interface
is not created when the machine reboots , the server runs 9.0-p3

here is the incriminated part of the /etc/rc.conf file

ifconfig_bce2="up"
ifconfig_bce3="up"
cloned_interface="lagg0"
ifconfig_lagg0=" laggproto lacp laggport bce2 laggport bce3"
ipv4_addrs_lagg0=" xxx.xxx.xxx.xxx/24"
defaultrouter="xxx.xxx.xxx.xxx"

Note : if I create manually the lagg0 interface everything starts well ...

thanks for any info
