Problems accessing Sony DRU-810A DVD drive

I'm getting the same problem, but I've got:

Ubuntu (not Kubuntu) 5.10
linux-image-2.6.12-10-k7

I'm getting it with data (ISO) DVDs as well. I discovered this when trying to burn. When I tried reading the data after, I'd get these errors. It's also possible that burning doesn't work either, but I have no way of confirming that. ;)

If this affects dapper, please add a linux-source-2.6.15 target to this bug.

I'm still getting these errors in Dapper, more specifically linux-image-2.6.15-23-k7. I'd also like to point out that once these errors occur, the only way to eject the DVD is by rebooting.

A bug has already been open upstream:

http://bugzilla.kernel.org/show_bug.cgi?id=6540

I could write to a DVD+RW using K3b 0.12.14 on a default Kubuntu 6.06 LTS release with KDE 3.5.3 packages downloaded from kubuntu.org.

Kernel is 2.6.15-26-386

My DVD-drive on Sony VAIO VGN-FS115MR stops reading disc after some time. I tryed DVD+RW, CD-R

Dapper, kernel 2.6.15-26

This is still a problem in Edgy, discs cannot be read.

It looks like this bug was never assigned as it should have been according to https://wiki.ubuntu.com/KernelTeamBugPolicies.

I am having this same problem with a Lite-On DRW-5S163. DVD and CD playback is slow resulting in CD audio that stutters/skips. DMA is show as enabled according to hdparm. I am running Ubuntu 6.10 edgy with kernel 2.6.17-11-generic

This finally works in Feisty. Yay!

Doesn't look like it. I still see those errors in Gutsy. The system log is flooded with them. Could this bug be the same as Bug #98670 . What happens if you do # hdparm -w /dev/hdc ?

The 18 month support period for Edgy Eft 6.10 has reached it's end of life. As a result, we are closing the linux-source-2.6.17 Edgy Eft kernel task.

Hardy Heron 8.04 was recently released. It would be helpful if you could test the new release and verify if this is still an issue - http://www.ubuntu.com/getubuntu/download . You should be able to test your bug using the LiveCD. Please let us know your results. Thanks.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

Unfortunately this bug report is being closed because we received no response to the last inquiry for information. However, the Intrepid Ibex 8.10 Beta release was most recently announced - http://www.ubuntu.com/testing/intrepid/beta . If you are able to confirm this is still an issue with this most recent release please feel free to reopen this report. To reopen the bug report you can click on the current status, under the Status column, and change the Status back to "New". Thanks.

Setting the status to fixed. The problem disappeared in Hardy and should not reappear in Intrepid.

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.
