Linux – ACPI BIOS Error / AE_NOT_FOUND

acpiarch linuxdebugginglinux

I'm getting these error messages every single time I reboot my desktop (and a couple of more I don't know how to retain when it's shutting down, but those are not relevant to this question so far):

[gorre@uplink ~]$ journalctl -p err..alert

I found this article that states someone can add this line: echo "disable" > /sys/firmware/acpi/interrupts/gpe6F to /etc/rc.local, but I'm not sure if that's the correct solution…moreover, if that's only "patching" the error messages, but not fixing the underlying problem ‒ if any.

Or maybe should I wait for an upgrade?

I'm using:

[gorre@uplink ~]$ uname -a
Linux uplink 4.16.8-1-ARCH #1 SMP PREEMPT Wed May 9 11:25:02 UTC 2018 x86_64 GNU/Linux

…and this is my hardware:

  • Corsair RMX750 (750 Watt) 80+ Gold Fully Modular Power Supply
  • Intel Core i7-8700 (BX80684I78700) Processor
  • Asus Prime Z370-P
  • Corsair Force MP500 M.2 2280 240GB NVMe PCI-Express 3.0 x4 MLC SSD
  • Corsair Vengeance LPX 32GB (2 x 16GB) 288-Pin DDR4 SDRAM DDR4 2666 (PC4 21300)

UPDATE

New kernel 4.19.13-1-lts update:

$ uname -a
Linux uplink 4.19.13-1-lts #1 SMP Sun Dec 30 07:38:47 CET 2018 x86_64 GNU/Linux

…and the error/warning messages are finally gone!

Best Answer

Your hardware is too new sort of speak.

The bugs you are seeing are harmless and may persist for some time.

You could try upgrading your BIOS, that is utmost priority.

Then, you could try installing intel-microcode non-free package.

See if these two options work for you first.

Today, I have assembled a computer with the very same CPU and seeing the same bugs. On just another motherboard.

Update 2018-Dec-1

The error on my Dell laptop with very recent UEFI BIOS update is still persistent as per log:
