I previously posted a near identical error to linux-ide.
http://article.gmane.org/gmane.linux.ide/18375
Specifically, I could trigger it by running 'smartctl -d ata -S on

Same sata_nv controller, two different drives, many different cables.
Reproducible over 7 systems [two different models of Tyan mobo] that I
have.
