That is a pretty terrible changelog. And I don't recall my reasoning tbh. It was around the time of F17 development where we disabled a lot of stuff, so it may have just been overly optimistic that it was unused. Unless someone else has a good reason not to, we can reenable it. (How well it works however is unknown to me) Dave _______________________________________________ kernel mailing list kernel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/kernel
