Dmesg: ACPI BIOS Error (bug): Could not resolve symbol [^^RP28.PXSX.WIST]

Framework Laptop 12 Linux

I am a Framework Laptop 12 Batch 1, gray color user. I am seeing the following errors related to the ACPI, BIOS, and USB-C. Is that a problem? How to suppress the errors?

$ cat /etc/fedora-release
Fedora release 42 (Adams)

$ uname -r
6.15.5-200.fc42.x86_64

My BIOS info is below. I picked up the command from this page.

$ sudo dmidecode | grep -A3 'Vendor:\|Product:' && sudo lshw -C cpu | grep -A3 'product:\|vendor:'

These warnings are only an issue if you are experiencing a problem. :slight_smile:

Yeah, I noticed them too…
But (personally) they don’t bother me, there will always be errors and warnings.
That’s just the way it is. :slightly_smiling_face:

Batch 2 here with BIOS version 3.7. I see the same BIOS bug on Ubuntu 26.04 with linux 7.0.0-15.15:

My expectation from a Linux-friendly company like Framework is that they will care and fix this BIOS bug.

BIOS version 3.7 with Nobara 43 (7.0.5-200) same errors but they do not seem to be affecting anything. :confused:
