ACPI errors flood dmesg.

Hello to everyone!

I don't know when this happen, I think it was in a kernel update but recently trying to read dmesg I find an ACPI error flooding the logs:

[186263.598191] ACPI Exception: AE_AML_OPERAND_TYPE, While resolving operands for [OpcodeName unavailable] (20170531/dswexec-461)
[186263.598199] ACPI Error: Method parse/execution failed \_SB.PCI0.LPCB.EC._Q81, AE_AML_OPERAND_TYPE (20170531/psparse-550)
[186263.989694] ACPI Error: Needed type [Reference], found [Package] ffff994a81c273a8 (20170531/exresop-103)

I don't why this happens. All my hardware works perfectly without any problem.

All I want to do is suppress that text from the dmesg log.

Regards.

Re: ACPI errors flood dmesg.

There are lots of previous postings on this - for instance...

https://bbs.archlinux.org/viewtopic.php?id=223804

which mentioned those messages are usually harmless, so please search before posting.

You cannot suppress kernel messages from the dmesg log and it would be a mistake to try to do so.

Re: ACPI errors flood dmesg.

@i_love_r34 do the messages repeat?  If not was there some ACPI event that triggered the message so late after boot?
@paulkerry the timing of the messages is somewhat unusual unless the system took over two days to boot.

Re: ACPI errors flood dmesg.
