Vanilla 2.6.24-rc5 plus this patch:
=========================================================
[ INFO: possible irq lock inversion dependency detected ]
2.6.24-rc5 #1
---------------------------------------------------------
events/0/9 just changed the state of lock:
(&mc->mca_lock){-+..}, at: [<c0411c7a>] 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: [<c0133c57>] run_workqueue+0x87/0x1b6
#1: ((linkwatch_work).work){--..}, at: [<c0133c57>]
run_workqueue+0x87/0x1b6
#2: (rtnl_mutex){--..}, at: [<c03abd50>] linkwatch_event+0x5/0x22
#3: (&ndev->lock){-.-+}, at: [<c0411b61>]
mld_ifc_timer_expire+0x17/0x1fb
