Stew, Thanks for the quick reply AND all the hard work. None of this helped. It is as if the kernel doesn't recognize the device is a cd-rom. It does see the drive at the proper place in the scsi chain. The drive is correctly reported after booting in the KDE Control Center > Information > SCSI, and during boot process. I did some experimenting with different scsi devices. If I add a hard drive, the kernel creates correct device files in /dev/scsi/*. It does the same with ide devices. BUT, it doesn't do a thing with a scsi CD other than create an empty /dev/scsi/host0/bus0/target3/lun0. I tried two different cd drives with the same result. It doens't seem to recognize that it is a CD-Rom drive or a block device even though it correctly gets the info from the drive at boot: /var/log/messages <snip> Mar 8 11:45:56 G3 kernel: Vendor: SONY Model: CD-R CDU948S Rev: 1.0j Mar 8 11:45:56 G3 kernel: Type: CD-ROM ANSI SCSI revision: 02 Mar 8 11:45:56 G3 kernel: scsi1 : MESH I'm also getting a boot message that is something like "/etc/rc.d/rc.modules line 17 234 segmentation fault" that might be related. I can't find the error in any of the logs, but it does flash by during the boot messages. Coud this be a bug? Thanks Tom L
