Hi,

I'm a quite happy Sparc64 user (Ultra5), and recently I had the chance
to get a "real SMP machine" - an Axil 311 with two SM41 modules.  (Yes,
I know that this is slow as hell, but it's SMP!!! - and I'm a big fan of
these oldish machines).

Installing 1.6.3 on the Axil 311 went flawlessly, but of course that's
uniprocessor only.

Then I tried cross-compiling a 2.0G release on the Sparc64 (because it's
5 times as fast), and booting the resulting GENERIC.MP and GENERIC
kernels.  Didn't work.  "OK, so the cross-build is weird".

Now I built a kernel on the 1.6.3 sparc system locally, using the
netbsd-2-0 tagged sources as of 2004-07-27.  Building took 8 hours :-) but
eventually finished with:

copied that kernel to /netbsd, and tried booting into it...:

... which is not *really* what I had hoped to see here... - but it's the
same error I got with the sparc64->sparc cross-compiled GENERIC.MP kernel,
so at least it wasn't a cross-compiling problem.

The GENERIC.UP kernel (cross-compiled) fails like this:

Now I'm looking for some advice how to go ahead.  

The machine itself did work fine with SunOS 4.1.4 (and sees both CPUs,
amazing enough).
