It boots on the 32-bit PowerMac example.

It panics on the two examples of 64-bit types 
of PowerMac, both types dual socket but
1 core each vs. 2 cores each.

The kernel and world were non-debug builds
(with symbols).

Typo above, should have been: getnewbuf

So I installed the artifact.ci.freebsd.org
-r357545 kernel and kernel-dbg (-r357529
was not available).

But is failed earlier for the example
64-bit PowerMac tried. 32-bit booted okay.

But I'll report details for this one in a
separate submittal for the earlier problem.
