The attached patch modifies drivers/ata/sata_vsc.c to only set the cache line size to 0x80 if the default value is zero. Apparently zero isn't allowed due to a bug in the chip, but I've found performance is much better with the (non-zero) default instead of 0x80. Signed-off-by: Nate Dailey <nate.dailey@xxxxxxxxxxx>
