Unfortunately for this FYI the attempt to produce a dump
failed and so all the information that I have is what I
first captured from the console output: a backtrace.
The context was head -r317015 on a Pine64+ 2GB. At the
time I was experimenting with trying to build a vm.raw
from my own build of FreeBSD. The (root) file system
is on a USB SSD off of a powered USB hub.
