The system is not a notebook, and I don't think it is ACPI. ACPI
has always refused to load on this system,

  BIOS 639kB/261120kB available memory
  acpi: bad RSDP checksum (155)

Well, this could be a problem I suppose, but it has always been
this way, and it's been running the 5.x branch fine up to 5.2.1-R.

Here is the complete dmesg(8) for more info on what else the system
has,
