I’d try the kernel version used in 23.11 to see if that fixes it. Add boot.kernelPackages = pkgs.linuxKernel.packages.linux_6_1; to your config (make sure to add it before the closing }) and sudo nixos-rebuild switch . You can also try older versions, like linux_5_19. If it doesn’t fix the problem it might be that the ACPI error is a red herring and the problem is something else entirely, in which case it’d be more difficult to diagnose, and I’d recommend just staying on 23.11 for now and only taking the new packages that you need from 24.05. There’s a great post on how to do this here: discourse.nixos.org/t/…/2 (probably also in the docs somewhere but I couldn’t find it easily).
