Bad news. :( 2.6.24-rc7 + patch #1 (bonding: fix locking in sysfs 
primary/active selection):

bonding: bond0: setting mode to active-backup (1).
bonding: bond0: Setting MII monitoring interval to 100.
ADDRCONF(NETDEV_UP): bond0: link is not ready
bonding: bond0: Adding slave eth0.
e1000: eth0: e1000_watchdog: NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX/TX
bonding: bond0: making interface eth0 the new active one.
bonding: bond0: first active interface up!
bonding: bond0: enslaving eth0 as an active interface with an up link.
bonding: bond0: Adding slave eth1.
ADDRCONF(NETDEV_CHANGE): bond0: link becomes ready

[ INFO: possible irq lock inversion dependency detected ]
2.6.24-rc7 #1
---------------------------------------------------------
events/0/9 just changed the state of lock:
  (&mc->mca_lock){-+..}, at: [<c041255a>] mld_ifc_timer_expire+0x130/0x1fb
but this lock took another, soft-read-irq-unsafe lock in the past:
  (&bond->lock){-.--}

and interrupts could create inverse lock ordering between them.


other info that might help us debug this:
4 locks held by events/0/9:
  #0:  (events){--..}, at: [<c0133d33>] run_workqueue+0x87/0x1b6
  #1:  ((linkwatch_work).work){--..}, at: [<c0133d33>] run_workqueue+0x87/0x1b6
  #2:  (rtnl_mutex){--..}, at: [<c03ac644>] linkwatch_event+0x5/0x22
  #3:  (&ndev->lock){-.-+}, at: [<c0412441>] mld_ifc_timer_expire+0x17/0x1fb
