On IA the driver would be stalled until an i/o write completed. On iop13xx the driver is free to continue running. Perhaps someone with more knowledge about the sata_via hardware can answer if this would be an issue, because everything thus far looks correct in the iop13xx code. > -- > Martin Michlmayr > http://www.cyrius.com/ -- Dan - 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
