Bug report https://bugs.launchpad.net/ubuntu/+source/linux/+bug/782746 affects me. I also have a Aspire Timeline 5810TZ. It was a problem with prior releases too (back to Lucid). I had to go in an edit fstab to create an entry for the drive. I just had to do a install (rather than upgrade) of 11.04 (passwd policy would not accept a new password I entered and changed it to something else - lost access - should I report that as a bug?). I chose to do a fresh install. The CD/DVD drive is happily recognized during the install, but once the install is complete there is no desktop/fstab activity. udisks shows the drive and media also, but udisks --monitor-detail does not register a media insertion, though it does register a media ejection.
WORKAROUND: Change BIOS setting for SATA mode from AHCI to IDE. Forgot about that.
