    IMO it would be worthwhile to track this down. It's a clear indication
    that something is wrong somewhere.

    Could it be connected with the way the boot kernel hands control over
    to the image kernel? Presumably ACPI isn't prepared to deal with that
    sort of thing during a boot from S5. It would have to be fooled into
    thinking the two kernels were one and the same.
