m400 with updated tables (that are correctly overriding not appending)
provided via INITRD override. I am looking at why it's not working.

[    0.000000] ACPI: Table Upgrade: override [SPCR-HPE   -ProLiant]
[    0.000000] ACPI: SPCR 0x0000004FF7F30000 Physical table override, new table: 0x0000004FFFFF0000
