Gordon" To: current@FreeBSD.ORG Subject: 2.2.5 identying SCSI disk as Unknown device Mime-Version: 1.0 (generated by tm-edit 7.106) Content-Type: text/plain; charset=US-ASCII Sender: owner-freebsd-current@FreeBSD.ORG X-Loop: FreeBSD.org Precedence: bulk I have done some additional investigation since my previous message (2.2.5BETA hanging in Boot). I have compiled a custom kernel using the RELENG_2_2_5_RELEASE tag that is identifing my root disk as an unknown device and hanging in the boot. This is on a machines that work great with custom kernel using the same config file on 2.2.2. I have changed scsi/scsi_debug.h to define DEBUGTARG to 0. Can anyone suggest where I should look to find out what is the probe to fail? The following in my copy of messages (I copy by hand so some mistakes are possible) that appear on the screen during boot bt0: Bt445S/ 0-ISA(24bit) bus bt0: Your card cannot DMA above 16MB boundary.
