Will do.

Meanwhile, before I got around to building a kernel with debug options
enabled, I had another hang.  Got it into DDB successfully, but then I
managed, while looking for a way to switch between CPUs (the man page is
wrong in this respect), to get DDB to look at something it shouldn't
have, so it just said "fatal pag", and that was that.

I did get a backtrace of CPU 0, though, and it looked interesting:
