Since commit cc0e40700656b09d93b062ef6c818aa45429d09a, there is a problem if you have the 8021q module loaded and you then attempt to enslave a VLAN challenged interface. This is because VLAN 0 is automatically added to the bond, and the new bond_vlan_used() function simply checks for an empty list in bond->vlan_list without taking into account that VLAN0 might be on the interface.
This specifically affects IPoIB interfaces in a bond if you do a down/up cycle on the bond post-boot (during boot, the bonding module is loaded prior to the 8021q module, so everything is fine).
Let me know if further information or testing is needed.
