[Simh] PDP-11 Ultrix 3.1 Debugging

Hi SIMH folks,

Is there anyone who can help with debugging why an Ultrix 3.1 kernel won't
boot on my real PDP 11/23?  2.9BSD boots fine so I know it isn't the
hardware.  I have kernel sources and lots of extra printf's inserted but it
looks like maybe my line time clock just isn't running correctly.  Please
respond off-list, this isn't really a SIMH specific question.  Thanks!
