kernel: ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PR00._CPC]

Describe the bug I see this messages at boot since linux 5.12. It seem not cause any issue, but it's annoying.

I think that is very common. It is a bug in your BIOS, that the kernel is complaining about. Most firmwares are not completely standards compliant and are thrown onto the market as soon as they can barely boot Windows. You can probably patch the kernel to omit it.
