The Zip 250 which chokes on MWDMA SET_XFERMODE sometimes have "Floppy" appeneded to its model number. Quirk it too. http://bugzilla.kernel.org/show_bug.cgi?id=8563 Signed-off-by: Tejun Heo <htejun@xxxxxxxxx> Cc: Hans de Bruin <bruinjm@xxxxxxxxx> --- It seems the Zip 250 mwdma failure on libata doesn't seem to be libata's fault after all. IDE also fails SET_XFERMODE on this drive but IDE simply ignores the error and continues to operate in MWDMA mode, so I guess we can remove the 'temporary fix' comment or add another quirk type - ATA_HORKAGE_SETXFER_MAY_FAIL - and use it. Anyways, for the time being, this should do. drivers/ata/libata-core.c | 2 ++ 1 file changed, 2 insertions(+) Index: work/drivers/ata/libata-core.c =================================================================== --- work.orig/drivers/ata/libata-core.c +++ work/drivers/ata/libata-core.c @@ -3774,6 +3774,8 @@ static const struct ata_blacklist_entry { "SAMSUNG CD-ROM SN-124","N001", ATA_HORKAGE_NODMA }, { "Seagate STT20000A", NULL, ATA_HORKAGE_NODMA }, { "IOMEGA ZIP 250 ATAPI", NULL, ATA_HORKAGE_NODMA }, /* temporary fix */ + { "IOMEGA ZIP 250 ATAPI Floppy", + NULL, ATA_HORKAGE_NODMA }, /* Weird ATAPI devices */ { "TORiSAN DVD-ROM DRD-N216", NULL, ATA_HORKAGE_MAX_SEC_128 }, - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
