Distros usually know better and don't build in the generic driver. It's built as a module and used only as the last resort. > I guess it should at least say: > > *If unsure, say N.* > > It did no harm prior to 2.6.22 though. That didn't to any harm probably because ATA quirk code reserved the area for libata during PCI initialization, so the generic driver couldn't grab the port before libata. Now that the quirk is gone, the generic driver grabs the first IDE channel before libata and you don't have dma for your drive. cc'ing Bartlomiej. Bartlomiej, I think it would be better not to default to Y for CONFIG_IDE_GENERIC. For most cases, it just causes misconfiguration and confusion these days.
