Hmmm... looks like configuration went well but media presence polling is
causing the problem.  "hal-disable-polling /dev/sr0" will disable the
polling.  Can you please do that and see whether the drive is usable?

[root@picard ~]# hal-disable-polling --device /dev/sr0
Polling for drive /dev/sr0 have been disabled. The fdi file written was

/etc/hal/fdi/information/media-check-disable-storage_model_DVD_A__DH20A3P.fdi

Okay.

Inserted CD into drive: drive light came on for about 20 seconds, but
nothing happened.

Checked /var/log/messages and nothing there.

Left it sitting there for 5 minutes or so and checked /var/log/messages
again and still nothing there.

As media presence polling is disabled, the system won't notice whether
the media has changed or not.

Mounted the CD as root:
[root@picard ~]# mkdir /mnt/cdrom
[root@picard ~]# mount -t iso9660 /dev/sr0 /mnt/cdrom/
mount: block device /dev/sr0 is write-protected, mounting read-only

The command took about 1 minute to complete. I was then able to browse
the CD, however each change of directory took approximately 10 seconds
to read.

Hmmm...

I then ejected the CD:
[root@picard ~]# eject /dev/sr0

again, this took about 20 seconds to eject the CD.

After the eject, still nothing in /var/log/messages.

Tried inserting and ejecting another couple of times.

I verified that the CD was readable in my external CD drive and then put
the CD back into the main drive and started writing up the results so far.

As I've been typing, the drive has been spinning up and down several
times and this time when I checked /var/log/messages I found what is
attached.

Is there anything else I can provide in order for you to find the problem?

Can you please try kernel parameter "libata.force=2.00:udma33" and then
"libata.force=2.00:pio4"?  Depending on which distro you're on and
whether libata is built into the kernel or not, you'll need to use
different method to actually get the parameter passed to libata.

Thanks.
