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. ahd0: <Adaptec 39320 Ultra320 SCSI adapter> port 0xb000-0xb0ff,0xa800-0xa8ff mem 0xfa8f8000-0xfa8f9fff irq 29 at device 6.0 on pci4 ahd0: Defaulting to MEMIO on ahd0: Reserved 0x2000 bytes for rid 0x14 type 3 at 0xfa8f8000 ahd0: Reading VPD from SEEPROM...ahd0: VPD parsing successful ahd0: Reading SEEPROM...done. ahd0: STPWLEVEL is on ahd0: Manual Secondary Termination ahd0: Primary High byte termination Enabled ahd0: Primary Low byte termination Enabled ahd0: Secondary High byte termination Disabled ahd0: Secondary Low byte termination Disabled ahd0: Downloading Sequencer Program... 752 instructions downloaded ahd0: Features 0x101, Bugs 0x8ffe3f, Flags 0x43f1 ahd0: [MPSAFE] ahd0: [ITHREAD] aic7902: Ultra320 Wide Channel A, SCSI Id=7, PCI 33 or 66Mhz, 512 SCBs -- -- David (obrien_at_FreeBSD.org) Q: Because it reverses the logical flow of conversation.
