Hallo all,

I'm trying to upgrade an old 386 to 'current.  I've supped up to today, but
after booting on a freshly built kernel, init dies with a SIGBUS.

I'm totally stumped.  This happened before when building a -current kernel
from 1.0 toolchain; I figured there was a bug/incompatibility with the 1.0
toolchain and the -current tree (although I had built a new gas), so I booted
with the 1.0A GENERIC kernel on sup.netbsd.org and upgraded with the binaries
on munitions.wasabi.com.  Again, a new kernel makes init die with a SIGBUS.

Attached is the kernel config file I'm using.  Can anyone give me a clue as to
what I'm doing wrong?  (It's worth pointing out that I built a kernel with
the INSTADP config file, and init still died :-( ).

This is a 386/16, 8MB, IDE disk.

Thanks!

--Ken
