  I will provide more details on request.

  The Micron ClientPro 766Xi systems have the ACPI blacklisted due to a
falsely identified ACPI signature in the /sys/dev/acpica/acpi_quirks table
which is marked as ACPI_Q_BROKEN.
  This system has been in use for quite some time with 5.2.1-RELEASE with
ACPI activated without any sign of problems. I have manually overriden the
blacklist with hint.acpi.0.disabled="0" in /boot/device.hints; again, no
sign of problems.

  The Micron ClientPro system has the "PTLD  RSDT" ACPI signature which
is mistakenly identified as one of the two following entries in the
acpi_quirks table (the only ones with the "PTLD" pattern):

# Compaq Armada 6500
name:           Compaq_Armada_6500
oem:            FADT "PTLTD "  "  FACP  "
oem_rev:        FADT = 0
quirks:         ACPI_Q_BROKEN

# Compaq Presario 1925
name:           Compaq_Presario_1925
oem:            FADT "PTLTD " "  FACP  "
oem_rev:        FADT <= 0x06040000
quirks:         ACPI_Q_BROKEN

  Boot a recent 5.3-STABLE on any machine with a "PTLD" ACPI signature and
it will get blacklisted.
