Re: "attempt to access beyond end of device" on DVD

[Jacek Poplawski]

OK, I was wrong previously.

I don't need to reload sr_mod, I only need to remount DVD.

The reason I was wrong is I was suspecting that DVD remounts itself
after eject, but looks like it doesn't. Also it means that the problem
is different than 3 years ago, because I am sure I was remounting DVD
by hand and now I use some automount feature of Arch Linux / GNOME3.
