Hi,

ruiktest ~ # /tmp/acpidump
Could not get ACPI tables, AE_BAD_HEADER

It seems there is a bug in ACPICA, coreboot is using revision 0 (ACPI 1.0) if
there is no XSDT. But ACPICA expect always ACPI 2.0 style which have a len
record. This is bit more complicated, coreboot creates a header with revision 0,
but provides all other fields as it would be ACPI 2.0, but SeaBIOS correctly
strips that.

I created a bug report at ACPICA:

Thanks
Rudolf
