> ACPI: OEMB (v001 A M I  AMI_OEM  0x10000530 MSFT 0x00000097) @ 0x3ff8e040
>  >>> ERROR: Invalid checksum

Evidence of a shoddy BIOS, but not related to the failure at hand.

The acpidump output shows that this table claims a length of 102 bytes.
But the checksum across 102 bytes is non-zero.  It is possible that the
BIOS writer got the checksum right but the length wrong, as the
checksum after 46 bytes is zero.  Perhaps some buggy proprietary OS
recognizes the OEM-specific "OEMB" as a fixed length structure
of 46 bytes and errantly lets this BIOS through its test suite...

Linux ignores any table with a bad checksum.  But as Linux doesn't
recognize an OEMB table, it would ignore it even if the checksum were valid.

Whatever this table is, it is non-volatile:
 BIOS-e820: 000000003ff8e000 - 000000003ffe0000 (ACPI NVS)
