Cannot eject CD/DVD disc tray

[Joe]

The normal operation of my internal CD/DVD player has changed when upgrading from Ubuntu 9.04 to 9.10, kernel 2.6.31.11. Prior to this upgrade, I could open the disc tray by manually pushing the eject button on the unit, with or without a disc inserted. After the upgrade and once a disc is inserted and mounted, I can no longer eject a disc or open the disc tray by manually pushing the eject button. I can eject the disc by selecting the disc, and choosing Eject from the menu. I cannot open the tray after this. The only way to open the disc tray is to perform a restart or shutdown. After reboot the unit works normally until I insert a disc. During the time a disc is inserted, normal operations seem to work such as playing audio files or reading data. As a point of reference, if I reboot to my Windows Vista partition, all CD/DVD unit operations work as expected.

This exaxt same problem has beed observed and reported as a question https://answers.launchpad.net/ubuntu/+question/84046 . The user may report a bug. I find it encouraging that I am not the only one with this problem.

[Joe (jgsylvesterjr)]

I akso verified this behaviour on 9.10, kernel 2.6.31.10 .

Same for me with IO error while trying to read from a dvd disk: https://bugs.launchpad.net/ubuntu/+bug/436931 And this - the same with cd's: https://bugs.launchpad.net/ubuntu/+bug/436187, but without io errors, I can read cd disks.

What priority does this bug have? Does anyone have any questions to us, that would help him to track down the problem?

Hi Guys,

This is actually a duplicate of bug 397734 so I am marking it as such. Please continue to track this issue at that report. There is already a developer working on a fix. Thanks.
