Some ACPI errors

Hello,

I have Arch Linux updated with the latest Kernel (5.8.13).

When I put in the terminal:

dmesg | grep ACPI

I get the following two errors:

ACPI Warning: SystemIO range 0x0000000000000B00-0x0000000000000B08 conflicts with OpRegion 0x0000000000000B00-0x0000000000000B0F (\_SB.PCI0.SMB.SMB0) (20200528/utaddress-204)

ACPI: [Firmware Bug]: BIOS _OSI(Linux) query ignored

I don't know what they mean or how I can isolate them.

Re: Some ACPI errors

The second message means the manufacturer of the firmware expects it to be used exclusively with Other OS .
Usually linux is able to workaround this, sometimes we have to pretend to be that Other OS .

The first message requires more info to determine if it could give problems.

Re: Some ACPI errors

I have a similar line; I narrowed it down to a conflict with the Super-IO chip my mobo uses (NCT-6793D).

In order for the chip to properly monitor, I have to put this in my kernel command line:

acpi_enforce_resources=lax

And, that brings that message up.

It's never caused any problems other than that line in dmesg.

How can I solve the second message?

what does that kernel command line do?

Re: Some ACPI errors

Really the best option here is to just ignore them. You can't fix your firmware not responding to the fact that your using Linux and it largely doesn't matter, and the other is simply an information that the acpi declares certain information incorrectly.

The only thing that can fix these properly is an UEFI update, otherwise you shouldn't worry too much.

The UEFI is now up to date.

What do you mean by "ignore"? You mean the option "acpi_enforce_resources = lax"?

Re: Some ACPI errors

You can ignore both messages.

Like @V1del says, the

ACPI: [Firmware Bug]: BIOS _OSI(Linux) query ignored

is due to the way ACPI is implemented in your BIOS.  While your BIOS may be up to date, it still has incompatibilities with the Linux kernel.  Unless (and until) your hardware maker and BIOS developer fix the BIOS, you'll get that warning.

If you don't see any errors, you can safely ignore it.

Your other message

ACPI Warning: SystemIO range 0x0000000000000B00-0x0000000000000B08 conflicts with OpRegion 0x0000000000000B00-0x0000000000000B0F (\_SB.PCI0.SMB.SMB0) (20200528/utaddress-204)

is caused by a resource conflict between ACPI and some other piece of software (most likely lm-sensors).

If your hardware monitoring (fans, temps, etc) is working you can ignore this message, too (and don't even worry about the command-line parameter in my first post).
