Please configure DDB according to the instructions in the developers handbook, as well as INVARIANTS, INVARIANT_SUPPORT, DEBUG_VFS_LOCKS, WITNESS and DEBUG_LOCKS in your kernel. Then run the following DDB commands when the system hangs: show lockedvnods ps alltrace (or at least 'trace <pid>' for each value of <pid> listed in show lockedvnods) and provide the resulting output (screen capture/serial console log/etc).
