Comment 13 for bug 1892547

"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)."

ACPI Machine Language (AML)
https://wiki.osdev.org/AML

The programming language equivalent for AML.
ASL is compiled into AML images.
This is the language that the DSDT is written in.

If you need to fix your DSDT, you'll have to write at least a little bit of ASL.

Differentiated System Description Table (DSDT)

An OEM must supply a DSDT to an ACPI-compatible OS.

"The DSDT contains the Differentiated Definition Block, which supplies the implementation and configuration information about the base system. The OS always inserts the DSDT information into the ACPI Namespace at system boot time and never removes it."
