But in your previous posting, the aic proc routines said this: > Target 6 Negotiation Settings > User: 40.000MB/s transfers (20.000MHz, offset 127, 16bit) > Goal: 20.000MB/s transfers (10.000MHz, offset 8, 16bit) > Curr: 3.300MB/s transfers > Channel A Target 6 Lun 0 Settings > Commands Queued 1065 > Commands Active 0 > Command Openings 1 > Max Tagged Openings 0 > Device Queue Frozen Count 0 Which is the AIC driver's way of saying narrow async.
