Dmesg and /var/log/messages show repeated call traces when a bonding device is brought up in balance-alb mode or during failover. Regardless of the call trace messages, the bond functions correctly.

Call traces:
bonding: bond0: setting mode to balance-alb (6).bonding: 
bond0: Setting MII monitoring interval to 100.ADDRCONF(NETDEV_UP): 
bond0: link is not readybonding: bond0: enslaving eth0 as an active interface with a down link.bonding: 
bond0: enslaving eth1 as an active interface with a down link.tg3: eth0: Link is up at 1000 Mbps, 
full duplex.tg3: eth0: Flow control is on for TX and on for RX.bonding: 
bond0: link status definitely up for interface eth0.bonding: 
bond0: making interface eth0 the new active one.RTNL: assertion failed at net/ipv4/devinet.c (986)

Call Trace: 
<ffffffff80146c94>{kthread+0} <ffffffff8010beca>{child_rip+0}


These messages are only warnings that the RTNL lock has not been locked and can be ignored.  The bond is functioning normally.

Additional Information

Steps to reproduce:
1. Install SLES 10 SP2.
2. Configure the bond with mode=balance-alb and miimon=100 as parameters to the bonding driver.
3. Restart the network with /etc/init.d/network restart.
4. Observe the above mentioned traces in dmesg and /var/log/messages.
