The nIEN bit in the device registers control interrupt generation on ATA devices. However ATA devices don't generate interrupts except on command completion or during command processing so if you have no I/O outstanding you won't have any interrupts anyway. With funky new stuff like AHCI and NCQ this isn't so simple but for simple ATA as with the ata_piix driver it is. - 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
