And to confirm that, applying the following patch to sata_mv for 2.6.26.3
makes the HDD led work again as well:
--- a/drivers/ata/sata_mv.c
+++ b/drivers/ata/sata_mv.c
@@ -131,7 +131,7 @@ enum {
MV_GENIIE_FLAGS = MV_COMMON_FLAGS | MV_6XXX_FLAGS |
ATA_FLAG_PMP | ATA_FLAG_ACPI_SATA |
- ATA_FLAG_NCQ | ATA_FLAG_AN,
+ ATA_FLAG_AN,
CRQB_FLAG_READ = (1 << 0),
CRQB_TAG_SHIFT = 1,
So somehow enabling NCQ is at the root of the issue.
Cheers,
