It should have pretty much the same effect as removing the 'return 1;', however calling ata_port_abort() is more in line with libata's new-style error handling. /Mikael --- linux-2.6.21-mm1/drivers/ata/sata_promise.c.~1~ 2007-05-05 22:24:41.000000000 +0200 +++ linux-2.6.21-mm1/drivers/ata/sata_promise.c 2007-05-05 22:25:21.000000000 +0200 @@ -653,6 +653,8 @@ static void pdc_error_intr(struct ata_po qc->err_mask |= ac_err_mask; pdc_reset_port(ap); + + ata_port_abort(ap); } static inline unsigned int pdc_host_intr( struct ata_port *ap, - 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
