ACPI error messages and some other messages during boot

Hi everyone… again!

So after installing Manjaro, I have been seeing these “ACPI” error messages that appear in the following order on two successive windows-

I have found posts in this forum with similar problems faced by other users. I found this with an explanation on the problem.

Obvously, I can’t understand what’s being said, nor whether it’s suited completey to the problem I’m having! :confused::confused:

Is there anything wrong with my system/kernel/or anything I should worry about? Is there any way to get rid of these messages? They significantly increase the boot-up time!

Also, sometimes I see some messages simillar to messages displayed when I tried to install arch- they all start with the word “ok” enclosed with third bracket:

[ok] message

It’s like my system is being built right before my eyes- those types of messages!

Is this normal? Sorry I couldn’t take pictures of these messages, they don’t appear every time I start my PC…

Here’s my PC specs:

Thanks in advance!:slightly_smiling_face:

Many threads already on this.

The explanation is there, and in other threads, I don’t know what else to add. If you really want to understand this technically I’d use the Arch wiki to bone up :slight_smile: .

Bottom line these “errors” are benign, I get them on both my laptops too.

No they don’t.


I concur. My wife’s laptop does the same thing, and my desktop always shows the clean line. There’s absolutely nothing wrong with the system.

I suspect that Apollonius thinks they contribute to boot time because they are visible. If they were not visible, there would be no perceived extension in boot time.

Thanks for clearing things up guys! :smiley:

Happy to help where I can.

In layman terms…

What is happening:
Linux is investigating your system ACPI capabilities and your BIOS is reporting that some ACPI functions are available. However, when Linux tries to access them, they are not there. As such a warning is issued and Linux removes that ACPI function from its list.

Why is it happening:
Your BIOS is declaring ACPI functions without implementing them. This happens either because the BIOS is actively hiding them from the you (some BIOS like to report only to Windows operating systems), or because the BIOS code is buggy or of poor quality.

Is it bad?
Not usually, no. AE_NOT_FOUND exceptions are handled by the Linux boot process just fine. It just means that certain ACPI capabilities will be disabled. Those that the boot process revealed to be inaccessible. Of course. if any of those functions are important to you for some reason, or is a standard acpi function expected in every system, then indeed this could be bad. But the latter case will often result in a failed boot, which is not the case here.

What can you do:
Your BIOS settings may have ACPI options that allow it to work better with Linux. Look for anything of the kind in your motherboard model manual. You may also see these problems go away by updating your BIOS, since many times vendors patch these errors when they are reported. So look on the board manufacturer support website for BIOS upgrades to your board.
