I have an ancient Pentium machine(*) that I've been keeping up to
date using freebsd-update. It has run everything fine up through
11.3-RELEASE-p11. However it does not like the 11.4-RELEASE kernel.

The old 11.3 kernel still boots fine.

The kernel file is good and there's nothing in loader.conf that
should cause a problem.
# md5 -r /boot/kernel/kernel

Any suggestions?
(*) I occasionally have to pull data off 5-1/4 inch floppies and this
machine is equipped to do that.
