If ATA CD/DVD drive has no media in system boot time, there is a pause before kernel creates cd0 devices with message: cd0 at ata1 bus 0 target 0 lun 0 cd0: <_NEC DVD_RW ND-3540A 1.01> Removable CD-ROM SCSI-0 device cd0: 33.000MB/s transfers cd0: Attempt to query device size failed: NOT READY, Medium not present Script /etc/rc.d/devfs is runned BEFORE devices cd0,pass0,etc are created and any paramters in /etc/devfs.conf does not applies to these devices. >How-To-Repeat: Compile FreeBSD kernel with device atapicam FreeBSD host must have CD/DVD Drive of course. Define any parameters in /etc/devfs.conf with device cd0 e.g.: perm 0660 cd0 Reboot FreeBSD (CD/DVD must NOT have media inserted in boot time) Check device permissions ls -l /dev/cd0 >Fix: Workaround: run /etc/rc.d/devfs start by hand after boot. Or insert "sleep 15" in the head of /etc/rc.d/devfs >Release-Note: >Audit-Trail: >Unformatted:
