--- Comment #3 from dsamms at nw-ds.com ---
I had also opened a thread in the stable mailing list 

https://lists.freebsd.org/pipermail/freebsd-stable/2018-June/089073.html

The problem is NOT a kernel bug, but related to the loading of optional kernel
modules that needed recompiling. 

Commenting out ALL port based kernel modules in both /boot/looder and
/etc/rc.conf fully resolved the problem. I was running both Nvidia and
VirtualBox as well as CBSD. I did not think the modules were the problem as the
crash happened so early in the boot sequence and gave ZERO explanation for the
crash.

Would suggest "we" make it clear in the upgrade instructions to disable ALL
optional kernel modules. I expect Nvidia to fail and require a recompile before
working with a new version of FreeBSD, but in the past I have always been able
to boot to single user mode.
