Spurious "ACPI-1287 ... Method execution failed ..." messages

[supraexpress at globaleyes.net]

With a relatively current CURRENT on an MSI 875P-Neo (MS-6758)
motherboard, I see the following spurious about "ACPI-1287..." messages,
but this does not seem to affect the system boot or anything else.
