We don't really care much about sync, and other crap that happens during shutdown >amd: pid 5064 proc c1852004 vmspace/map c19034fc flags 0 Amd is trying to unmount a filesystem and is stuck in genfs_lock And the million $ question is: Is amd trying to unmount because of the shutdown, or because of the periodic mount timeout? If the second, do we have a locking race during unmount? Unfortunately looks like you'll have to reboot and redo the test to answer this. christos
