That is the thread I remembered. Unfortunately it was "fixed" by use of the ahci driver. As mine is 9.0-Stable, ahci is already there. Also, my disks are SATA, but they are connected to a 3Ware raid as RAID-1 and they look a SCSI disk (da0) to the system. I guess I'll build a kernel with KDB and try booting with a disk in the drive. I'll also try your suggestion, Ian, and try booting with DMA off. not that the drive will be terribly useful without it. If the problem is the same one David had with 9-Current a year and a half ago. Thanks, Adam and Ian. -- R. Kevin Oberman, Network Engineer E-mail: kob6558@gmail.com
