Firstly, one small comment: shouldn't the pcvt termcap entry have
a line-number entry? By default, pcvt has 25 lines, but it's
termcap :tc=:'s the vt100 entry, which has 24 lines.

Now, to recap the problem from my previous message... I am
trying to get the tar_files's latest kernel up and running.
I've got it compiled, and it loads and autoconfig's. If I let
it run in multi-user mode, it reboots immediately. If I start
in single-user mode, init will prompt me for the shell to be
run - but if I press enter or enter /bin/sh, the machine will
reboot. These reboots do _not_ put me into ddb. And I do have
COMPAT_10 set (my config.new file follows at the end of this
message).

Now, the GENERIC config.new file has the following lines:
----------------------
isa0	at root
eisa0	at root
pci0	at root
----------------------
But when I try that, make complains about a missing eisa_machdep.c
file. So I've commented eisa0 and pci0 out, which shouldn't matter,
since I only have an eisa bus.

I have been able to get /bin/csh loaded (the ignominy!) from init's
singleuser prompt, and can even to type a few characters to csh, but
the kernel vm_faults seconds afterwards with this:
----------------------
vm_fault(f8190474,0,1,0) -> 5
kernel: pagefault trap, code=0
----------------------
which sends me to ddb. When I do a `ps' from ddb, I get:
----------------------
pid proc     addr     uid ppid pgrp flag   stat em comm   wchan
3   f8688a00 f97ff000 0    1   3    004086  3   0  csh    ttyin f8650a00

1   f8684200 f97f8000 0    0   1    004084  3   0  init   wait f8684200
0   f8197a28 f81b1000 0   -1   0    000204  2   0  swapper
----------------------
and there are a few messages about getting a trap in ddb.

Does this give anybody a clue yet?

Here is my config.new: DUMMY_NOPS doesn't make a difference.
