Faults listed at start

[Legion99]

I have an HP ProBook 455 G9 with AMD Ryzen 5 5625U with Radeon Graphics and AMD ATI 04:00.0 Barcelo GPU.

I installed Deb 12.6 on a clean install then had to install kernel 6.6.13+bpo-amd64, to get the combined WiFi / Bluetooth chip to work.

Everything works well, except the fingerprint scanner, which I am not worried about.

On boot, I get a bit of a laundry list of errors, I got them with the original 12.6 installed kernel as well. They are more of an annoyance and don't appear to effect the machine at all. But I would like to get rid of them if I can, or at least fuigure out what is going on.

From dmesg the errors are:

Code: Select all

Any information gratefully accepted. Thanks

Code tags please for terminal text and errors etc. Fixed it for you this time.

ACPI errors can usually be ignored afaik.

The message is self explanatory:

Code: Select all

ACPI BIOS Error (bug)

This is a BIOS bug, fixable only by the BIOS vendor.

Again, probably a BIOS bug, or an ACPI feature the kernel doesn't know what to do with. Vendors (particularly laptop vendors) don't bother to test their hardware or BIOS implementations with Linux.
There are a few command line parameters you micht play with to see if you can get it to behave better, e.g. 'acpi_osi='Windows 2020' and the like, see the kernel ACPI docs.
Then again, if it's not causing observable problems I'd leave it be.
