=============================================
[ 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
