Linux ACPI errors after BIOS update

I have a NUC7i5BNH running arch linux. After updating the BIOS from version 0057 to version 0063 (BNKBL357.86A.0063.2018.0413.1542), some ACPI error messages have started appearing during boot:

kernel: ACPI Error: [_SB_.PCI0.RP05.PXSX] Namespace lookup failure, AE_NOT_FOUND (20170728/dswload2-191) kernel: ACPI Exception: AE_NOT_FOUND, During name lookup/catalog (20170728/psobject-252) kernel: ACPI Error: Method parse/execution failed \_SB.PCI0.RP04.PXSX, AE_NOT_FOUND (20170728/psparse-550) kernel: ACPI Error: [_SB_.PCI0.RP09.PXSX] Namespace lookup failure, AE_NOT_FOUND (20170728/dswload2-191) kernel: ACPI Exception: AE_NOT_FOUND, During name lookup/catalog (20170728/psobject-252) kernel: ACPI Error: Method parse/execution failed \_SB.PCI0.RP08.PXSX, AE_NOT_FOUND (20170728/psparse-550)

After downgrading to BIOS version 0057, the errors no longer appear

I'm using a standard Linux 4.14 LTS kernel:

Linux nuc 4.14.35-1-lts # 1 SMP Thu Apr 19 10:38:59 CEST 2018 x86_64 GNU/Linux

Any ideas what might be causing this?

Hello tomxland,

 

 

I understand that you have started to experience issues when updating the BIOS of the system.

 

 

First, I would like to point out at the fact that Linux* is not a supported O.S on that NUC, you can refer to to the link below for a list of the different supported O.S:

 

 

https://www.intel.com/content/www/us/en/support/articles/000005628/mini-pcs.html Supported Operating Systems for Intel ® NUC Products.

 

 

Now, since this problem occurred after doing a BIOS update it could be highly possible that there was a problem when the BIOS was updated, you can attempt to fix this by doing a BIOS recovery. You can follow the steps on the link below in order to do a BIOS recovery for the unit:

 

 

https://www.intel.com/content/www/us/en/support/articles/000005532/mini-pcs.html NUC BIOS recovery.

 

 

Let us know the outcome please.

 

 

 

I hope this helps.

 

 

 

Regards,

 

David V

Not really a BIOS/UEFI issue - this is more of a general ACPI issue with Linux in general.

Most of these are "warnings" and not errors...

Check out Launchpad over in Ubuntu space, and you'll find a number of similar bugs...
