Comment 19 for bug 439137

OK, I installed the Jaunty kernel as requested with no problem. Unfortunately, and surprisingly, it worked the same as the Karmic kernel. None of my media will automount, and once I open and then close the tray without media it locks up. I even saw the same USB errors during boot, which also surprised me. I thought they were caused by the Karmic kernel but I guess not. However, I don't have any problems with any of my USB devices so this is not an issue.

After this I wanted to do a sanity check so I restored my Jaunty installation (I use SystemRescueCD and have my user data on a separate partition so I can quickly switch operating systems) and all the CD and DVD media works great. There are simply no problems with my ODD drive under Jaunty, so something is definitely wrong with Karmic.

I'm going to do a clean install of the Karmic beta now and I'll report back when I'm done. I know this is a frustrating problem, but hang in there and I will be happy to continue to run any tests you need. I see that there are a lot of people with ODD problems under Karmic, while others have no problem at all, so this appears to be a serious issue that needs to be worked out before the final Karmic release.

It will only take me a few hours to install the Karmic beta and after that it might be useful to run tests under Jaunty and Karmic and see what the difference is. Other than that I don't have any suggestions and how to proceed with the debugging, but you're the dev and I'm sure you'll think of an effective strategy!
