I have a vmcore for this panic. I have saved off the installed kernel
directory for future examination.

The only delta in my source tree on this machine is a patch
to the pagezero.S file, which I've been running for several months,
so I know it's not that.
(https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=199151 for the
delta, if you care. I need to benchmark this more fully, but just
haven't gotten around to doing it yet.)
