I had to create it manually with mknod. When you make CD devices with MAKEDEV, it makes the number of devices you specify on the command line. Specifying 'cd1' makes 1 device, cd0. You want to type 'sh MAKEDEV cd2' to make cd0 and cd1 devices. > Maybe the mixture of ATAPI and SCSI cdrom confuses the system. > The systems unit numbering is not reflected correctly in the messages. I suspect your device nodes may be messed up. Can you send the output of: camcontrol devlist -v ls -l /dev/*cd* Make sure you CC your reply to FreeBSD-gnats-submit@FreeBSD.ORG so it goes into the audit log for this PR.
