Description Brian 2008-05-19 04:26:11 UTC
Latest working kernel version:2.6.24-17-generic (buildd@palmer) (gcc version 4.2.3 (Ubuntu 4.2.3-2ubuntu7)) #1 SMP Thu May 1 14:31:33 UTC 2008
Earliest failing kernel version: Unknown but see Ubuntu bug # 44233 - over 1 year old. The Ubuntu bug report indicates that it is not only Ubuntu, but also Mandrake and other distros and suggests that there may be a problem of hardware compatibility, or that there may be a problem with disks written by Nero. 
Distribution: Ubuntu
Hardware Environment: Fujitsu Siemens Amilo AM 1451 Laptop with DVD+ -RW ND6650A
Software Environment: Linux only as above. No other O/S
Problem Description: UDF formatted CD fails.

Oops pop-up error message:
   Cannot mount volume.
   Invalid mount option when attempting
   to mount the volume 'UDF Volume'

Output from manual mount:Output from manual mount:- (both fstabs)
   $ sudo mount -t udf /dev/scd0/ /media/cdrom0
     mount: block device /dev/scd0 is write-protected, mounting read-only
     mount: wrong fs type, bad option, bad superblock on /dev/scd0,
            missing codepage or helper program, or other error

Replacing cdrom user entry with "iso9660,udf user" or with "auto user" made no difference at all.  ISO9660 disks mount perfectly, UDF does not. The UDF disk mounts perfectly in a Windows XP machine.

Steps to reproduce: Place UDF formatted CD in drive and try to mount.

I have the same issue with Kernel 2.6.25.4-30.fc9.i686 from Fedora.
