Processes in state '*inp' are waiting for an inpcb lock, suggesting a deadlock or lock leak. Can you compile your kernel with invariants, witness, ddb, etc, and do a bit of kernel debugging? You can find basic instructions in the handbook; what I'm particularly interested in is the output of "alltrace", "show alllocks", "show allpcpu".
