-- Information about the crash:
I'm storing many DVD into a local drive.
Mounting and UnMounting IDE DVD 'sometime' volumes hangs the unload procedure but DVD eject.
Icons of ejected DVD still remain into the 'Places' panel as into the 'Device notifier'
So I've mounted another volume and so on...
The crash appens randomly ejecting a not mounted dvd volume.
Not useful information into dmesg log:
