This cannot happen :-)
A brief description: SBI is the main bus on unibus/Q22 bus
equipped machines, and it can have uba adapters attached to it.
During autoconfig, the kernel checks whether the machine has
a system bus or if it is equipped like a VAXstation. But in
your case, neither of these can be determined.
I would like you to:

Use B/43 MUA0 when booting the kernel. (Forces loading of the
kernel symbol table).
When the kernel stops, examine the following variables and mail
me the results:
db> x/x cpu_type

db> x/x cpunumber

db> x/x 0x20040004

then I can check what is special with your computer.
