So just make that: if (lba48) { tf->hob_nsect = 1; qc->nsect = 256; } /* continue */ and it should work fine. Similarly for 48-bit lba, 0 means 16^2 sectors. -- Jens Axboe - : send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
