Latest working kernel version: 2.6.20-16

Distribution: Ubuntu-8.04_ppc
Hardware Environment: ibook G4
Software Environment:
Problem Description: when I tasted to mount a audio cdrom, mount failed, only for audio cdrom; other cdrom works correttly.

Steps to reproduce: 

pietro@trip:~$ mount /media/cdrom0
mount: block device /dev/hdc is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/hdc,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

pietro@trip:~$ dmesg | tail

You're not supposed to mount an audio cdrom since it has no filesystem on it as your log suggests. If you want to access it, do so without mounting it. See http://www.tldp.org/HOWTO/CDROM-HOWTO/index.html for details.

Hmm, so what was the final conclusion about this report?  not-a-bug?
