Please attach your yast logs (http://en.opensuse.org/Bugs/YaST), your /etc/sysconfig/kernel and output of 'hwinfo --cdrom'.

Comment 6 Matej Horvath 2007-06-22 07:49:31 UTC

initrd should be build with the above modules.

Comment 9 Hannes Reinecke 2007-06-22 10:24:01 UTC

Why should the CD-ROM modules be in the initrd? Do we try to boot from them?
I guess not.
It's more a problem of udev not loading the required modules.
Reassigning.

Comment 10 Kay Sievers 2007-06-25 22:50:03 UTC

Kernel 2.6.22 exports MODALIAS for SCSI devices. Udev no longer loads these modules with special rules. Christian, please let sysconfig call modprobe scsi modules.

Comment 11 Christian Zoz 2007-07-06 07:43:13 UTC

From now on modprobe will be called from udev directly. Not longer from hwup.

Comment 12 Janos Toberling 2007-07-06 10:35:45 UTC

I have the same problem with an external Pioneer DVD writer attached by an IDE-USB converter to a USB2 port.
After loading sr_mod manually system founds it.
