ACPI BIOS errors when booting

Hello, I installed Arch on my new notebook and I get the following error messages when booting:

ucsi_acpi USBC000:00: error -ETIMEOUT: PPM init failed
ACPI BIOS Error (bug): Could not resolve symbol [^^^^NPCF.ACBT], AE_NOT_FOUND (20240827/psargs-332)
ACPI Error: Aborting method \_SB.PCI0.SBRG.EC0._Q83 due to previous error (AE_NOT_FOUND) (20240827/psparse-529)

ACPI Error: Aborting method \_SB.PEP._DSM due to previous error (AE_NOT_FOUND) (20240827/psparse-529)

Are these harmless, or should I file a bug report somewhere?

Thank you

Re: ACPI BIOS errors when booting

Likely it's an issue with your manufacturer's ACPI tables in their UEFI. Update if possible.
Disable any "CSM" or other compatibility modes, and change any settings which offer "Linux" or "Other OS" settings to those.

These things happen, and might not have much impact.
