Thinking about the trace again... Emil: what happens in the trace before this? Is there ever a call to the ixgbe_get_settings? Does a NETDEV_UP or NETDEV_CHANGE event ever hit the bond_netdev_event function? Could you describe your test that reproduces this? I'd like to see if I can set it up locally. -J --- -Jay Vosburgh, jay.vosbu...@canonical.com
