It's the optical drive choking up on commands (TEST_UNIT_READY) used for polling for media presence events. As it's PATA and the hard drive shares bus with the optical drive, while the optical drive is choking, the hard drive can't access the bus so hard drive access also stalls. Disabling media presence polling should work around the problem for now. Long term, I think we shouldn't use TUR for media presence polling. Windows doesn't use it and devices with crappy firmware which chokes on repeated TUR aren't too rare. That's in the pipeline but unfortunately I don't think it will be ready for this release cycle. It's gonna be a pretty pervasive change. :-( So, for now, "hal-disable-polling /dev/sr0" seems like the only solution.
