11.4-RELEASE i386 won't boot

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.

  /boot/kernel/kernel text=0x128f22b data=0xe9748+0x2890f4
syms=[0x4+0xea3e0+0x4+0x1797e9]
  /boot/entropy size=0x1000

  Hit [Enter] to boot immediately, or any other key for command prompt.
  Booting [/boot/kernel/kernel] in 9 seconds...

  Type '?' for a list of commands, 'help' for more detailed help.
  OK set boot_verbose
  OK boot
  Booting...

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

# cat /boot/loader.conf
console="comconsole vidconsole"
hint.acpi.0.disabled=1  # removing this doesn't help
beastie_disable="YES"

Any suggestions?

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