The error messages are caused by BIOS bugs, and they cannot be fixed in Ubuntu.
OC07 error in descriptions is declared but not defined in ACPI DSDT, i.e. External (OC07, UnknownObj). The OEMB in #6 has a checksum (i.e. one of OEMx) is a OEM-specific table and that's probably used in Windows only (maybe a workaround). Many ACPI functions are optional and it is sometimes okay to fail when these features are not used or can be disabled. If you have not obvious failures you can ignore them. -- 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/1892547 Title: [ 0.172384] ACPI Exception: Could not find/resolve named package element: OC06 (20170831/dspkginit-381) [ 0.172444] ACPI Exception: Could not find/resolve named package element: OC07 (20170831/dspkginit-381) Status in linux package in Ubuntu: Incomplete Bug description: [ 0.172384] ACPI Exception: Could not find/resolve named package element: OC06 (20170831/dspkginit-381) ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: linux-image-4.15.0-112-generic 4.15.0-112.113 ProcVersionSignature: Ubuntu 4.15.0-112.113-generic 4.15.18 Uname: Linux 4.15.0-112-generic x86_64 ApportVersion: 2.20.9-0ubuntu7.16 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: xilion 1667 F.... pulseaudio CurrentDesktop: LXDE Date: Fri Aug 21 22:15:54 2020 HibernationDevice: RESUME=UUID=3a74be02-d33e-4932-8d91-4d1fa8672def InstallationDate: Installed on 2018-06-18 (795 days ago) InstallationMedia: Ubuntu 16.04.4 LTS "Xenial Xerus" - Release amd64 (20180228) IwConfig: lo no wireless extensions. enp0s29f7u2 no wireless extensions. enp1s3 no wireless extensions.
