Subject: ACPI disabled due to DMI failure or blacklisted year should be noted, as is done with other ACPI blacklisting
From: "Anthony Godshall, Ampro Computers, Inc." <agodshall@xxxxxxxxx>
IMHO, ACPI disabled due to DMI failure or blacklisted year should be noted,
as is done with other ACPI blacklisting.
This will help people troubleshoot when ACPI isn't working. Status quo is
a mysterious "ACPI Disabled" message without explanation on BIOS that
implements ACPI but not DMI. This is actually fairly common on embedded
x86 boards.
