[rhelv6-list] vlan issue with RHEL 6.3 kernel 2.6.32-279

[Werner Maes]

Hello

After upgrading from 6.2 to 6.3 I have a serious issue with the latest RHEL6.3 kernel: 2.6.32-279.el6
My vlan network configuration no longer works (no traffic on the vlan interface), however if I boot with my old 6.2 kernel 2.6.32-220.el6 all works fine. What has changed?

see below for configuration details.

cat ifcfg-vlan688 
BOOTPROTO=static
DEVICE=vlan688
IPADDR=10.x.y.z
NETMASK=255.255.252.0
NM_CONTROLLED=no
ONBOOT=yes
PHYSDEV=bond0
TYPE=bonding
USERCTL=no
VLAN=yes
VLAN_NAME_TYPE=VLAN_PLUS_VID_NO_PAD
