New question #708562 on Ubuntu-Certification: https://answers.launchpad.net/ubuntu-certification/+question/708562
Hello. I have Lenovo ThinkPad P14s Gen 4 (AMD Ryzen 7 PRO 7840U, Radeon 780M Graphics) with last bios uefi version 1.16 with installed ubuntu desktop 23.10 and I have issues with ACPI. During booting ubuntu I get an error messages: ACPI BIOS Error (bug): Failure creating named object [\_SB.MHSP], AE_ALREADY_EXISTS (20230331/dswload2-326) ACPI Error: AE_ALREADY_EXISTS, During name lookup/catalog (20230331/psobject-220) Then I cant change power-profile-daemon to "performance mode" but it is still in "powersave mode". Is there any chance that when I downgrade bios uefi to version 1.11 and install ubuntu 22.04 LTS these problems disappear or can you give me some advice how the mentioned problems solve?
