Usually with a CFA device it means you are not using a UDMA capable (and UDMA rated) adapter. Unfortunately while proper ATA cabling and devices have a negotiation system there isn't a way to discover this particular situation. The boot option "libata.dma=3" disables CFA DMA but leaves ATA and ATAPI DMA enabled for such cases. -- 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
