Comment 48 for bug 482419

I can confirm that this bug still occurs. Although I've been using this configuration for ~6 months, it bit me today. This is on a box running Ubuntu server, with two bonded interfaces. Bond0 failed to come up after a reboot, while bond1 did come up. After I got onto the box via bond1, a reboot worked - both bond0 and bond 1 came up. However, /var/log/messages still contains many lines of the below:

Apr 23 11:02:43 server1 kernel: [104080.510023] bonding: bond0: Warning: Found an uninitialized port

and many lines of:

Apr 23 11:05:14 server1 kernel: [ 16.985610] bonding: bond0: doing slave updates when interface is down.
