I can concur with this and confirm that turning off wide negotiation in the SCSI setup seems to correct this. 3 questions : 1) Does anyone have any more info on this 2) Is there updated driver code I can include in the kernel build 3) Having "newfs"-ed, would turning back on wide negotiation lead to more problems similar to the "newfs" problem Thanks Wayne
