Leaving - ap->ctl |= ATA_NIEN; => seems to work - the upper and "ap->last_ctl = ap->ctl;" => seems to work - the upper and "iowrite8(ap->ctl, ioaddr->ctl_addr);" => irq storm on request irq. ata_sff_check_status() does not report ATA_DRQ set so I don't know why the interrupt is comming. >Thanks. > Sebastian -- 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
