[ INFO: possible circular locking dependency detected ]
2.6.18-mm2 #1
-------------------------------------------------------
nash/1264 is trying to acquire lock:
(&bdev_part_lock_key){--..}, at: [<c0310d4a>] mutex_lock+0x1c/0x1f
but task is already holding lock:
(&new->reconfig_mutex){--..}, at: [<c03108ff>]
mutex_lock_interruptible+0x1c/0x1f
which lock already depends on the new lock.
the existing dependency chain (in reverse order) is:
