Ubuntu

optical drive un-mounts during playback, disk in no longer detectable until restart.

Asked by Ben

Everything worked in 9.10

Upgraded Ubuntu 9.10 to 10.04.

when computer is first started and a disk is inserted the disk mounts and begins play back fine. Between 1 - 20 min later the video freezes up or I get a message that says that the disk is not available. After which point the disk in the drive is no longer detectable. I can remove the disk and inset it again however it is not detected by the system until I reboot.

I then tried a fresh install. Downloaded the iso from the Ubuntu web site (US location) last night 5-10-10. It has the same issue.

I am trying to watch a movie from start to finish.

the drive should not be "un-mounting" during playback.

Any help would be greatly appreciated.

I can provide further info just let me know what is needed. I'm new to the Ubuntu world so use little words please! :)

When the drive unmounts, can you please run:

dmesg | tail -n 15

Thanks

Between the Bug and the Question I have been asked to run:

Have a websearch round and see what this means:

VFS: busy inodes on changed media or resized disk sr0

Could be helpful.

Thanks for the input. I've looked around and it does appear that "VFS: busy inodes on changed media or resized disk sr0" is a problem. However, I didn't see any fixes for it. The Bug report got a tag that says it effects the kernel . . .

hope there is a solution posted soon. Not being able to use my Drives is a Linux/Ubuntu show stopper for me. Perhaps I'll just down grade and stick with 9.10. Before I do that though is there any other info I could give that would aid in fixing this problem?

Well, I uninstalled Totem and Mplayer. Installed VLC and Banshee and now everything works just fine. Not sure if it was the programs or a update that fixed the issue, but last night I watched a whole movie so for now I'm declaring this a non issue.
