Does not automount CD except after bootup

[SilverWave]

Description: Ubuntu lucid (development branch)
Release: 10.04

Lucid 10.04 Beta1 plus updates.

If I boot up with a CD loaded then the CD appears on the desktop.
If ejected and another CD inserted this CD is not automounted.

Clean install but kept /home from previous Ubuntu 9.10

[Update]
Can access CD in VirtualBox (set the Guest to use sr0).

Just had a look at a backup and fstab looked like this prior to Lucid:

[bash (1bash)]

I am experiencing the same problem.

System: Lucid Lynx 32bit
Kernel: 2.6.32-19-generic || #28-Ubuntu SMP Wed Mar 31 17:46:20 UTC 2010

Noticed that dmesg if full of errors after inserting a CD or DVD into the drive. I do _not_ get these errors on a system (also running Lucid 32bit) where automounting works.

DMESG Output attached

@SilverWave: Can you check if you also recieve these sorts of dmesg errors?

[SilverWave (silverwave)]

The output is attached.

I work around this by creating:

/media/cdrom0

and adding the following to fstab:

/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0

I still need to run this from the terminal:

mount /dev/scd0

Installing Beta 2 today/tomorrow so we will see if this is still an issue.
