| I don't know about the error, but the ACPI warnings are quite common and usually can be ignored. |

i still don't notice any issues or symptoms, and i can't really reproduce these errors or coincide with anything i'm doing.. i've been ignoring them all.

did you update your bios?
Second you could manually fix your dsdt
ressource
https://forums.gentoo.org/viewtopic.php?t=122145
https://wiki.archlinux.org/index.php/DSDT
MAy I ask which hardware we are talking about? type model, bios version, anythign else which reveals which hardware it is. Mostly main logic board matters
--
I am also curious of the output of e.g. sysrescue-cd + dmesg
Is this a genkernel? |
