Subject: Re: 4.14 kernel and acpi INT3400:00: Unsupported event [0x86]

I have submitted a patch to suppress such messages. The INT3400 driver
currently handles 0x83 thermal-relationship-table-change event
only, and all other ACPI notification codes are unknown/irrelevant
to the INT3400 driver.

Thanks,
-Brian
