** Changed in: linux (Ubuntu) Status: Incomplete => Fix Released ** Changed in: linux Status: New => Fix Released -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/558926 Title: Open files on ejected media cause automount of new media to break Status in The Linux Kernel: Fix Released Status in “linux” package in Ubuntu: Fix Released Bug description: Open a file on a cdrom, perhaps as simply as changing the working directory of a shell to a location in /media/cdrom, then eject the disc. The filesystem is forcibly unmounted, so it no longer appears in df, mount, or /proc/mounts, though it appears to still actually be sort of mounted since you can run stat . from the shell. The kernel begins complaining filling /var/log/kern.log with messages like: VFS: busy inodes on changed media or resized disk sr0 At this point the drive has vanished from view in nautilus. It no longer appears on the places menu or in the computer folder. If you insert a different disc it also will not show up in nautilus and you can not mount it through the gui until whichever processes that still have file descriptors open on files on the ejected media are closed.
