include/acpi/acexcep.h:76:#define AE_NOT_EXIST EXCEP_ENV (0x0006) include/acpi/acexcep.h:212: EXCEP_TXT("AE_NOT_EXIST", "A required entity does not exist"), which means that the ACPI entity required for the memory region in SystemCMOS (the chip for the BIOS) doesn't have the required entity to handle it over, and the _Q33 GPE associated method for ACPI Machine Language, does not exist, the source code is missing, so, you have a certain base address in a certain device which doesn't have the required firmware to make it work, and ACPI complains over it, update the BIOS and the drivers of the device.
