There are two types of ACPI errors observed: AE_ALREADY_EXISTS and AE_NOT_FOUND
The former, AE_ALREADY_EXISTS, usually happens 1) when BIOS loads multiple SSDTs (in /sys/firmware/acpi/tables) that contains the objects with the same names (and usually the same functions too). Naming conflicts prevent kernel to load all of them correctly. 2) BIOS's ACPI methods are not serialized and multiple calls the same methods occur. I would guess we are seeing scenario 1 here. They are usually harmless because a copy of working SSDT is loaded while duplicated ones are discarded. The later, AE_NOT_FOUND, is the opposite. This occurs when BIOS does NOT load SSDTs and therefore kernel is not able to get information and perform accordingly. Neither types of error messages can be fixed without BIOS fixes. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1864895 Title: dmseg report multiple "ACPI Error" and "ACPI BIOS Error" Status in linux package in Ubuntu: Triaged Bug description: 'lsb_release -rd': Description: Ubuntu 19.10 Release: 19.10 'cat /proc/version_signature > version.log': Ubuntu 5.3.0-40.32-generic 5.3.18 'sudo lspci -vnvn > lspci-vnvn.log' as attachments.
