I had a brief look at this a little while ago, as I was looking at the hacks Debian applies to make 2.6.x IDE work on Atari/ARAnym. As I understood it the problem was some IDENTIFY command which needed to not byteswap (the hack byteswaps a second time). Can't the driver inspect the command type and choose whether to swap or not? I had a grand plan of writing a pata_falconide libata driver, but ran out of steam :-( -- 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
