CDROM issues after 8.04 upgrade

Mon Jun 9 23:55:49 UTC 2008

 	Greetings,

 	I just upgraded to Ubuntu 8.04 and discovered that my DVD+-RW drive is 
no longer available and won't automount.  I did some reading and made the 
following changes:

It was using /dev/hda in 7.10 because it was a IDE drive (not-SATA), This is 
legacy and not included in 8.04 (would have been nice if the upgrade had changed 
the device in fstab, but oh well).  The documentation now wants you to use 
/dev/scd0, so I changed this out in my fstab and rebooted, but I still have no 
CD drive.

I took a gander at the dmesg file and saw the relevant section

The above two lines repeat about 50 times...

All the devices associuated with the CD above are links to scd0, and I can't 
mount disks in scd0, so that is why the links don't work.

The amd line is listed as Bug: 39602 and was apparently closed without any 
solution being presented.

 	In either case, both of these seem to be new issues with 8.04.

Any ideas?
