I actually think that everything should work just fine with 4 bytes alignment, but the SBP-2 spec mentiones 8 bytes alignment for the S/G tables. So maybe device firmwares will expect it that way even though IEEE 1394 doesn't impose such a restriction even on transfers with a payload of a multiple of 8 bytes. -- Stefan Richter -=====-=-=== ---= -===- http://arcgraph.de/sr/ - To unsubscribe from this list: 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
