CD and DVD media fail to mount

[Max Ingram]

Binary package hint: nautilus

10.04 LTS

Upon upgrading from 9.10 to 10.04, CDs or DVDs of any kind fail to mount. Double-clicking the associated drive icon under 'Computer' produces no result. Attempts to mount discs using commands, "mount /dev/sr0" or "mount /media/cdrom0"result in errors, "mount: can't find /dev/sr0 in /etc/fstab or /etc/mtab" and "can't find /media/cdrom0 in /etc/fstab or /etc/mtab."

Attempted to solve issue with fresh install of 10.04 from disc. Disc was recognized on boot up and fresh install proceeded without errors. But issue persists under new install with identical results.

what does dmesg said about the mounting process? could you try to mount it and attach that log to the report? thanks.

[Max Ingram (eightlegged-steed)]

I haven't used dmesg before, so hopefully this is what you're looking for. I attempted to mount from the command prompt, got the usual error, and then typed 'dmesg'. This was the output.

kernel or driver problem, let's reassigned to linux where it can be triaged, thanks.

[Jeremy Foshee (jeremyfoshee)]

Hi Max,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, please run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 591243

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.

Okay, I burned a copy of the latest 10.10 ISO and ran it as a live CD. While operating under that environment, I was able to insert a CD into my secondary CD/DVD drive and have it recognized perfectly. I could play music off the CD, and it worked just like it should. Ejected and re-inserted the music CD several times and it worked great. So whatever you guys have changed in 10.10 seems to fix this issue.

I went back into 10.04 and ran the command requested for debug info.

I also installed what I think is the latest "upstream kernel", but I really wasn't clear on the instructions so I'm not sure if I did that correctly. I downloaded the most recent image under the Lucid directory (2.6.32-0206321505-generic_i386.deb) and installed it, then rebooted under that and the problem persisted without changes.

The most recent updates seem to have resolved this issue for me. My discs are mounting normally again.
