I'm resending this, in the hope that the lack of response last time
wasn't an indication that nobody's running -current on a 650 _and_
that nobody's got any good ideas for me to try...  :-)

I'm unable to get a current kernel to boot on my KA650...  It's
currently running a snapshot of current from sometime in February,
built from the tarballs of either the 14th or the 21st (I can't
remember now which date I actually fetched them, I'm afraid), so it
was all right back then.  I first tried to upgrade to the April 11th
tarballs, and when that failed, I waited a couple of weeks, and
fetched the April 25th kit.  I now have systems built from that
distribution running on my Sparcstation 2 and on my old i386 box, but
am unable to get a VAX kernel to boot.

If I build a kernel without UVM, as before, it merely prints out the
copyright banner and then executes a HALT instruction.  If I build it
with UVM, it gets a bit further: my normal configuration will then go
into a hang after it (correctly) identifies the CPU and memory, the
backplane and Q22 bus.  If I strip down the configuration, removing
support for all devices except what absolutely must be there to get a
compilable, theoretically runnable kernel, it instead executes a HALT
instruction at (approximately) the same time.

It seems something broke the KA650 support in the last two or three
months.  Is anyone running a fresh current on this processor?  Could
it be that something happened during the integration of UVM support?
I'll happily test any ideas anyone might have...

Oh, incidentally, there's one file that (for the April 25th tar balls,
anyway) needs to be compiled without -Werror, because of a conflict
between a set of common declarations of certain support functions, and
the special, static, inlined ones in the VAX port.  It looked
harmless, so I just built it thus:
