DVD Drive Not Accessible

[zenarcher]

I've having an issue with my internal SATA DVD drive with Kubuntu 9.10 Alpha 2.. The same issue existed with Alpha 1. I have Karmic on two computers here...one is fine, with a different brand of DVD drive.

The drive is recognized and identified in KInfoCenter and I can use it through K3B. However, if I put a disk into the drive...the disk is not found, nor can I see it in Dolphin. The same occurs no matter what disk I put in the drive. The same identical drive worked fine with Jaunty and earlier.

The drive I'm having the problem with is a Lite-On Model DVDRW LH-20A1S Rev. 9L08.

If I reinstall Jaunty, the drive once again recognizes when I've put a disk in it...not not with Karmic. The drive is the same one I used to do the Karmic install.

Thanks for the bug report.
Please insert the dvd in the drive, open a terminal and run the following commands:

dmesg
sudo mount /dev/dvd /mnt

Please attach the output of both commands as separate files.

[zenarcher (zenarcher-opensuse)]

I have attached the requested information. Incidentally, when the disk is inserted, the light on the drive and the hard drive light flash normally, as I would expect when the drive is working properly.

dmesg output

[am_public (am-public)]

System get I/O error when it tries to read dvd (end_request: I/O error, dev sr0, sector 121296). If the drive (with the same media) works with prevues version of Ubuntu it could be a regression in the driver.
Please follow instruction in https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies about how to add debug info to the bug report.
Thanks in advance.

[zenarcher (zenarcher-opensuse)]

Yes, I can reinstall Jaunty and the drive works fine with the same media. The media is a backup of my folders in Home, which I use with a reinstall (although I have tried other disks, as well). Everything works fine with Karmic on another machine, with a different brand of DVD drive, using the same disk, as well. The issue only occurs with Karmic Alpha 1 and Alpha 2.

I am very new to filing bug reports with Launchpad. This is the first bug I've filed, in fact. Could you please clarify for me, what I need to do now to get this bug to the proper place and source?

Thanks

[zenarcher (zenarcher-opensuse)]

I have run ubuntu-bug -p linux from a terminal and the report was sent, as best as I can tell. I'm assuming that is all I had to do?

[am_public (am-public)]

ubuntu-bug is usefull to create a new bug, in this case it where better use the command apport-collect (described below the ubuntu-bug) to attach debug information to this bug report. However it's not a great problem, I will set that bug as a duplicate of this one. I don't have to ask you anything else, but maybe some kernel haker could need some more info. Thank a lot.

[am_public (am-public)]

Please refer to bug 388401 for full debug log.

[zenarcher (zenarcher-opensuse)]

Thank you very much for the assistance. I'll be more familiar next time I have to file a bug in Launchpad. I'll be happy to provide any information I can, so long as someone can tell me exactly what they want and how I can get the information for them.

[am_public (am-public)]

You're welcome :) Thanks for your helpfulness.

I think I have a smiliar problem. On Jaunty, but not Hardy, my DVD drive doesn't burn DVDs. That is, k3b and Brasero don't see the DVD drive at all. In dmesg, suspicious activity:

Reading DVDs seems to work for me. I'm confident it's not a hardware issue.

[Krzysiek Kwasniewski (krzykwas)]

It seems I have encountered the same bug: https://bugs.launchpad.net/ubuntu/+bug/436931 I also get IO errors while trying to read from the disk, however after last updates dvd disks are mounted automatically.

zenarcher, thank you for reporting this and helping make Ubuntu better. Karmic reached EOL on April 30, 2011.
Please see this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

We were wondering if this is still an issue in a supported release? If so, can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command in a supported release from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
