I am experiencing this same problem since Jan 2007. I have the same motherboard but a different DVD-RW drive. When I first attempted to install linux on my newly built computer, the damned JMicron controller was unsupported, and so DVD drive access was impossible. About 3 weeks later support was added, and I have always figured that this behavior is a symptom of just poor support for this controller.

A workaround that I have been using for the past few months is just to keep a blank CD-RW (or some kind of media) in the drive at all times. It seems like this only happens when the drive is empty for more than a few minutes.

I would be interested in any advice anyone has to offer.
