    =============================================
    [ INFO: possible recursive locking detected ]
    2.6.18-rc5-mm1 #2
    ---------------------------------------------
    knodemgrd_0/2321 is trying to acquire lock:
    (&s->rwsem){----}, at: [<f8958897>] nodemgr_probe_ne+0x311/0x38d [ieee1394]

    but task is already holding lock:
    (&s->rwsem){----}, at: [<f8959078>] nodemgr_host_thread+0x717/0x883 [ieee1394]

    other info that might help us debug this:
    2 locks held by knodemgrd_0/2321:
    #0: (nodemgr_serialize){--..}, at: [<c11e76cd>]
    mutex_lock_interruptible+0x1c/0x21
    #1: (&s->rwsem){----}, at: [<f8959078>]
