I just tried ipoib/bonding with mainline kernel 2.6.27 and it works fine, as expected, see below. Can you repeat the exact sequence and see if it works for you, or send the settings that break bonding/ipoib on your system? I didn't use network scripts but this should be the issue if you use the directives that come with the ib-bonding package. $ modprobe bonding mode=active-backup miimon=100 $ modprobe ib_ipoib $ echo +ib0 > /sys/class/net/bond0/bonding/slaves $ echo +ib1 > /sys/class/net/bond0/bonding/slaves $ ifconfig bond0 10.10.5.62/16 up $ ping 10.10.0.90 & $ ifconfig ib0 down $ dmesg | grep bonding bonding: MII link monitoring set to 100 ms bonding: bond0: doing slave updates when interface is down. bonding: bond0: Adding slave ib0. bonding bond0: master_dev is not up in bond_enslave bonding: bond0: Warning: enslaved VLAN challenged slave ib0.
