Gelsema & Joćo,

Do you still have your U320 disks running as U160 disks with an Adaptec
U320 controller in 7.0 or 8-CURRENT? I also have this problem and I've
traced it down to the CAM "NEW TRAN" code.
----------------------------
revision 1.166
date: 2006/11/02 00:54:33; author: mjacob; state: Exp; lines: +0 -333
2nd and final commit that moves us to CAM_NEW_TRAN_CODE as the default.
----------------------------

Given that we're not seeing tons of reports of this issue, I wonder if
its related to either revision of the ASIC or firmware. For comparison
here is my information from a verbose boot.
