sata_inic162x can't do LBA48 properly yet. Whine loudly about it to

Does it simply fail? Or does it corrupt?
In my Windows experience, if you try to write data past ~128GiB and
you don't have LBA48 support you get a wraparound effect that causes
corruption of the data below ~128GiB. I've seen it happen several
times under Win2K in particular.
