[    0.000000] ACPI: undefined version for either FADT 4.0 or MADT 1
[    0.000000] ACPI: Error parsing LAPIC address override entry
[    0.000000] ACPI: Invalid BIOS MADT, disabling ACPI

Seems the MADT revision is not right, could you dump the ACPI MADT
(APIC) table and send it out? I will take a look :)

Thanks
