systemd ACPI Error

Postby abukva » 2017-02-20 18:33

I have Debian 9 with kernel 4.9.0-1-amd64, and after the update to this kernel I've noticed this error during systemd boot:

Code: Select all
[    0.599941] ACPI Error: [_PPC] Namespace lookup failure, AE_ALREADY_EXISTS (20160831/dswload-378)
[    0.599948] ACPI Exception: AE_ALREADY_EXISTS, During name lookup/catalog (20160831/psobject-227)


I've googled it but I could only find topic related to the dedicated GPU, I have integrated with i5-6440HQ.

Sorry for the late response, I've updated the bios (as suggested in gentoo forum) from Lenovo website but the messages still persist. I've read the bug report on bugzilla.kernel and I also did not notice any problems while I was using my system. Maybe for the now, the best solution would be to leave it as it is, or revert to the older kernel.

I face the same bug, it was suggested that there is nothing to do by Debian developers regarding it.
I doubt it will be solved even when Stretch will be a stable version.

Yes, I've noticed it.
It's clear that the problem is with the kernel.
It's present in every distro, you can find mentions in the net.
The question is: is it harmfull or not?
It's possible to find comments that no, it's only an information,
but I, like you, don't want to see red lines during booting.
When I see them I come to conclusions that something serious is broken.

I've read on one forum that maybe the problem was there for a long time but only now started to show errors. I did not notice any deterioration in a system performance or any glitches, so I will keep it like this for now. :|

And why not on all computers? Of the 3 I own (all running Stretch), only two gives this ACPI error. My DELL laptop does not. Weird.
NEC Spirit 550 P4 3.8GHz HT - 2GB RAM - nVidia 7600GT - Pioneer BDR-209DBK
ASUS Sabertooth P67 i7 3770K - 32GB RAM - 2x nVidia 660GTX SLI'd

I have ThinkPad T460p, maybe there is something with the newer hardware.
