(XEN) ACPI Error (tbxfroot-0218): A valid RSDP was not found [20070126]

I wonder if you're trying to use xen.gz on an EFI system. Is so,
you want to use xen.efi there instead if firmware doesn't set
up enough compatibility things in EFI Mode, or enable CSM if an
option like this is provided by firmware setup.
