Model: sun3 60
fpu: mc68882

This may be part of the problem. It appears that at some point in the
past life of this box, someone did the 68882 mod on it. I never caught
this before since it was never a problem on past SunOS or NetBSD
versions, but something here may be triggering it.

Right.. that's what I'm working on next... sadly, kernel compiles on
this poor guy takes a little while. :) Due to the problem we talked
about earlier  in the thread, GENERIC doesn't work on the 3/60 without a
recompile and some tweaks.
