 The machine is probably either panicking, or deadlocking due a locking
 error.  Enable WITNESS, DDB, INVARIANTS and kernel crashdumping, and
 try to obtain debugging information.  Leaving the machine out of X
 Windows may also help, because you'll see the panic message on the
 system console.  See the Developer's Handbook and for more details.
