Just to follow up to my report, the following patch seems to cure these
symptoms:
diff --git a/drivers/ata/sata_nv.c b/drivers/ata/sata_nv.c
--- a/drivers/ata/sata_nv.c
+++ b/drivers/ata/sata_nv.c

static struct ata_port_operations nv_generic_ops = {

- .hardreset = nv_hardreset,
+ .hardreset = ATA_OP_NULL,
.scr_read = nv_scr_read,
.scr_write = nv_scr_write,
};
Best wishes,
Chris.
