The troublesome part is here:

e1000: eth0: e1000_watchdog_task: NIC Link is Up 100 Mbps Full Duplex, Flow Control: RX/TX
e1000: eth0: e1000_watchdog_task: 10/100 speed: disabling TSO
bonding: bond0: link status definitely up for interface eth0.
bonding: bond0: making interface eth0 the new active one.
