The program "xcdplayer" running on 2.0.5-RELEASE with a BusLogic adapter
exhibits problems also -- sounds like it could be related.

For example, if you let a CD play all the way out, and then hit play
again, you get a hang. Or sometimes pressing play when the cd is paused
causes a hang.

In all cases the box entirely freezes up.
