  What specificaly are the lines you enabled for SMP in the kernel?

  I believe that with 4.7+ there are only two lines needed:

  options        SMP                     # Symmetric MultiProcessor Kernel
  options        APIC_IO                 # Symmetric (APIC) I/O

  You may want to have the following in there too:

  options         SYSVSHM         # include support for shared memory
  options         SHMSEG=9        # max shared memory segments per process
  options         SYSVSEM         # include support for semaphores
  options         SYSVMSG         # include support for message queues

  Try that and let us know what happens.
