I tried late Saturday (4/10), Sunday (4/11) and today (4/12).  The working
kernel that I have is from 4/4.  I'm using the same config as from the
working kernel, and there doesn't appear to have been any relevant changes
in LINT.  I'm going to try blowing away my source tree completely and
re-cvsupping, but...

Does your CPU#1 launch right after the kernel loads, or does it wait until
the "normal" time?

things like Unix, relational databases, and Windows can make an appliance that
is inexpensive and easy to use if they choose to do that.  -- Scott Adams
