DU folks,

Sequence of events:
  We upgraded an NFS server.
  We didn't shut all the client systems down first.
  On this particular system (others rebooted fine), it would not
     boot up in multi-user mode.
       It would go through the /sbin/rc[23].d scripts then crash
         with a 'kernel panic'. (prior to the login prompt or the
         switch to CDE).
       After moving some of the latter rc3.d scripts, out it was
         evident that this wasn't it. (I could boot single user
         to do this).
       I recompiled a kernel on a whim and things started working
         again.
       Next day, the system crashed (while the user was on it).
       uerf reports:
 
          panic (cpu 0): pmap_ptptetoseg: not a _pagetable

Anyone know what this means and what this implies?
Is it hardware? Is there any reason for me not to believe
that the crashes before and the one crash after are not caused
by the same thing? (I have no reports from the prior crashes
as there was not enough room to save the crash dumps). This is
running on 4.0b

Thanks in advance,
