This machine has error log address range in NVRAM? According to ACPI 4.0a spec: """ 17.5.2.4.1 Error Log Address Range Resides in NVRAM If the Error Log Address Range resides in NVRAM, then when OSPM writes a record into the logging range, the record is automatically persistent and the busy bit can be cleared immediately. On a subsequent boot, OSPM can read any persisted error records directly from the persistent store range. The size of the persistent store, in this case, is expected to be enough for several error records. """ So it should not work with the same procedure.
