Just a sidenote, at some point (think 2.6.15) I had problems with sata_mv that *only* occurred with md raid levels 1,5,6 - everything was ok when multiple disks were separate filesystems. That was like 4 disks and 10 threads or so. So I'd recommend always testing also with raid. I'll leave the guessing about what might be reasons for that behaviour for others. - 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
