I assume that because you have a DECsystem, you are using a serial
console?  That's about the time it switches to the serial driver instead
of using PROM routines I think.  How old is the kernel you're trying
to boot?  Is it -current, or 1.2?  One thing that looks strange is the
priority of scc0.  On both the /240's and /260's here, the priority of
scc0 is 5, not 6 - scc1 is at priority 5...
