SEQADDR(0X173) SCSIRATE (0X93) Unexpected DT Data Phase The Katana is expecting us to use 20MHz DT transfers when the controller believes it has negotiated 40MHz ST. I have a Katana sitting on the shelf at home that worked the last time I tested against it, but perhaps I've recently broken something. It could also be that I have different firmware on my drive than you have. 4.0 did not support DT transfers at all which explains why 4.0 works for you. I'll let you know what I find out. -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
