First I've heard of any benifit to using ACPI on a motherboard that
does APM, particularly with how broken a lot of ACPI code (in FreeBSD
and on laptops and other machines) has been and ACPI in 4.x being
labelled experimental. None of it has sounded like something I wanted
to mess with on production machines.

These are production machines, I can't just pull them out of service
whenever I feel like it. None of the other machines I have that are
running 4.9-R or 4.9-STABLE are exibiting the same problem.

Intel sell motherboards they label as ServerWorks;
  http://www.intel.com/design/servers/buildingblocks/srsh4_spsh4/index.htm

I was told that this motherboard was a serverworks motherboard in part
because it had the serial console features I needed. I may have been
misinformed - I don't keep track of most PC things.

This is the motherboard I have;

I've been running 4.x on several of these motherboards for months with
no problems, until 4.9.
