Comment 4 for bug 1015199

I have the same problem as the original submitter. Setting blond-slaves and removing bond-primary still doesn't allow "ifup bond0" to bring up slave interfaces, it just hangs. I have to do "ifup -a" to work. While it all works fine at boot time, reconfiguring bonding interface with "ifdown bond0; ifup bond0" just leaves it in an unusable state.
