(In reply to crypt47 from comment #13)
On one host you'd run

$ <check out FreeBSD sources, use the releng/13.0 branch>
$ <edit sys/amd64/conf/GENERIC to enable INVARIANTS>
$ make buildkernel
$ tmpdir=$(mktemp -d)
# make installkernel DESTDIR=$tmpdir

Then copy over the ${tmpdir}/boot/kernel and
${tmpdir}/usr/lib/debug/boot/kernel directories to the affected host. 
Beforehand, rename the existing ones to /boot/kernel.old and
/usr/lib/debug/boot/kernel.old.  This way you can still select the old kernel
from the loader.

There's no need to update userspace, just the kernel.
