There are some confirming reports of problems with these drives under Linux (for example http://lkml.org/lkml/2007/3/4/178) so let's disable NCQ on these drives. [ I'm personally starting to wonder whether we shouldn't disable NCQ by default, and perhaps have a white-list. There seems to be a *lot* of drives that do this wrong.. - Linus ] Signed-off-by: Robert Hancock Acked-by: Tejun Heo Signed-off-by: Linus Torvalds --- diff --git a/drivers/ata/libata-core.c b/drivers/ata/libata-core.c index ddb3909d72..87b47bd318 100644 --- a/drivers/ata/libata-core.c +++ b/drivers/ata/libata-core.c @@ -3363,6 +3363,11 @@ static const struct ata_blacklist_entry ata_device_blacklist [] = { { "Maxtor 6L250S0", "BANC1G10", ATA_HORKAGE_NONCQ }, /* NCQ hard hangs device under heavier load, needs hard power cycle */ { "Maxtor 6B250S0", "BANC1B70", ATA_HORKAGE_NONCQ }, + /* Blacklist entries taken from Silicon Image 3124/3132 + Windows driver .inf file - also several Linux problem reports */ + { "HTS541060G9SA00", "MB3OC60D", ATA_HORKAGE_NONCQ, }, + { "HTS541080G9SA00", "MB4OC60D", ATA_HORKAGE_NONCQ, }, + { "HTS541010G9SA00", "MBZOC60D", ATA_HORKAGE_NONCQ, }, /* Devices with NCQ limits */
