In bond priority testing, we set the primary interface to eth1 and add eth0,1,2 to bond in serial. This is OK in normal time. But when in debug kernel, the bridge port that eth0,1,2 connected would start slowly(enter blocking, forwarding state), which cause the primary interface down for a while after ensalve and active slave changed. Here is a test log from Jakub's debug test[1].
