http://www.freebsd.org/cgi/query-pr.cgi?pr=165087 Occurs simply trying to use unionfs: mount -t unionfs -o noatime /usr /mnt insmntque: mp-safe fs and non-locked vp: 0xfffffe01d96704f0 is not exclusive locked but should be KDB: enter: lock violation Its possible to continue tho. Then locks encounter on every file/dir access under mounted path. It can be resumed from KDB, but sometimes leads to deadlock and system freezes at "db> " prompt.
