Did you also edit the modprobe.conf file?

Hi, I'm trying to configure a network bridge over a bonding without any success. Here is my configuration: ifcfg-eth0: DEVICE=eth0 HWADDR=00:1E:C9:E8:3F:E5 ONBOOT=yes USERCTL=no MASTER=bond0 SLAVE=yes ifcfg-eth1: DEVICE=eth1 HWADDR=00:1E:C9:E8:3F:E7 ONBOOT=yes USERCTL=no MASTER=bond0 SLAVE=yes ifcfg-bond0: DEVICE=bond0 ONBOOT=yes BRIDGE=br0 USERCTL=no ifcfg-bridge0: DEVICE=br0 TYPE=Bridge BOOTPROTO=static IPADDR=192.168.52.55 NETMASK=255.255.255.0 NETWORK=192.168.52.0 BROADCAST=192.168.52.255 ONBOOT=yes DELAY=0 eth0 and eth1 don't goes up... Am I doing something wrong ? Shouldn't I trying to do a bonding over 2 bridges ? Do anybody already tried such a configuration with success ?
