I am not sure if it is a bug in gnome or openvz patch; but it only happen in combination. Post here is anyone has the same problem or any idea how to fix/debug it, if no one has then I am going to file a bug report ! Smile

Step to reproduce.

* Compile kernel 2.6.27 with patch-briullov.1-combined.gz patched.
* Run Ubuntu Jaunty. Insert cdrom or usb storage ; gnome popup the window with content of device. Close window , right click the cdrom desktop ison select unmount or eject. Message saying can not be unmount / eject device is busy (or some other apps still trying to access it)

* Start a terminal, sudo to root, unmount /media/cdrom0 saying device busy. Run lsof | grep '/media' does not show anything.

* Logout of gnome, and switch to text console (Ctrl+Alt+F2 ); login sudo to root and I can unmount it. Or login but using another wm like icewm I can umount it.

* This does not happen with Ubuntu default kernel, Or non openvz patch 2.6.27 kernel (I tried 2.6.27.29)
