Your Ubuntu kernel is clearing the host protected area (the BIOS has

Set the boot option "libata.ignore_hpa=1". That defaults to zero
(respecting the BIOS) so that users don't accidentally blow away BIOS
partitions and restore images, except apparently Ubuntu patch it the
other way by default.
Thank you very much for clarifying this behavior.
Using "options libata ignore_hpa=1" and rebuilding initrd now lets
2.6.25.3 boot without problems.
Best regards, Peter.
