This is true also for atapicam driver. But since no device on atapicam bus is used during boot kernel does not wait for devices (particulary scsi cd device driver) to settle and start /sbin/init process quite early so /etc/rc.d/devfs is executed before /dev/cd0 is created. And lines concerning cd0 in /etc/devfs.conf are ignored. IMHO, kernel should wait for all devices initialized during boot process to finish initialization before starting userland stage of boot process (/sbin/init). >How-To-Repeat: >Fix: add kern.cam.scsi_delay="200" to /boot/loader.conf BUT this will affect all SCSI devices, not only atapicam. >Release-Note: >Audit-Trail: >Unformatted:
