[ INFO: possible irq lock inversion dependency detected ] 2.6.24-rc4-git7 #1
---------------------------------------------------------
events/0/9 just changed the state of lock:
(&mc->mca_lock){-+..}, at: [<c0412602>]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:

events/0/9 just changed the state of lock:
(&mc->mca_lock){-+..}, at: [<c0412602>]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.
Yes this is a bug in the bonding driver.
It's assuming that bond->lock is only ever held for writing in process context. Unfortunately our current set_multicast_list interface violates this constraint.
Now I do have a TODO item to fix set_multicast_list to not do that, but until that happens, bond->lock should always turn BH off, even on read lock.
Cheers,
