It's still > pretty safe but not as much as before. Nowadays, there are good number ata_generic is always safe unless you force it to grab every class device. By default it grabs only those devices we know obey the class interface well enough and for which we have no proper driver (usually because there are no documents). Ditto for ide/pci/generic. The trickier one is pata_legacy, which tries to be smart and knows about the known exception so *should* always be safe. The old IDE legacy driver lacks these smarts so in some cases will do the wrong thing even if loaded last. Alan
