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.
