Our host controller does NCQ, and we have drives (directly from manufacturers) that also do NCQ. I'd be able to do testing ... if somebody made the code changes to Libata. I just don't know my way around the SCSI layer, so I'd be groping around in the dark if I embarked on trying to figure this out. Anybody out there want to tackle this, as a joint effort with me? I can dedicate as much time as needed on my end. Cheers, -mat Mat Loikkanen Synopsys, Inc.
