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.
