It means your BIOS returns an incorrect object from the ACPI _GTF method which is used to figure out what ATA commands should be used to resume the hard drive properly. In this case the kernel just doesn't send such BIOS-provided commands. Usually these aren't necessary as the kernel knows how to re-initialize the drive itself, so it's likely not a serious problem.
