I actually got to this over the weekend. I did a rollback that appeared 
to work without a problem. After the rollback, all working again under 
11.2-RELEASE-p14. I then did 'pkg-static update -f' that appeared to 
update all packages where 'pkg update' said all were up to date. Then I 
did a normal 'pkg upgrade' and all packages updated as expected without 
issue. After a reboot to make sure all was good, I then proceeded with 
the upgrade once again...

     freebsd-update -r 11.3-RELEASE upgrade

All completed as expected, but when I rebooted after the first 
'freebsd-update install' was issued, I am now faced with 'BTX halted' 
without reaching the boot menu.

Is there something I can try for this issue to boot back into the OS?
