I wonder if this is related to the code

static int nv_hardreset(struct ata_link *link, unsigned int *class,
unsigned long deadline)
{
unsigned int dummy;

/* SATA hardreset fails to retrieve proper device signature on
* some controllers. Don't classify on hardreset. For more
* info, see http://bugzilla.kernel.org/show_bug.cgi?id=3352
*/
return sata_sff_hardreset(link, &dummy, deadline);
}

It seems especially suspicious given that 305d2a1a touches
sata_sff_hardreset...
