In mm, sata gets loaded before pata in libata land. In alan cox's patches it's the reverse. This results in different device names for the same config when switching between mm and release, which is bad, but is a problem that can be overcome with the use of labels instead of device names. Perhaps from a distribution standpoint, moving to a label method of describing what gets mounted where would be best, rather than worrying about scsi naming schemes or ide ones. Just think of the fun of a system with multiple usb storage devices and such. I'm just not sure if grub and the kernel "root=" parameter can handle it. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
