The drive (HP DVD Writer 640i) is somewhat suspect and that may account for the tray not acting as one might expect (that is, unexpected openings). It's currently in DMA/Ultra33 mode (as it had been prior to installing 10.0) and... so far, so good... for now. The non-name DVD drive (DVD & CD read only) clearly won't tolerate DMA in any form under 10.0 although it worked predictably under 9.3 (before I yanked it, last year, for the 640).

Sigh... I only wish that were so with 10.0. I don't think SUSE Linux 10.0 mis-behavior is totally random but it is clearly so boogered that the faults interact to the point where predicting failures is less successful than doing long term weather forecasting.
Please keep in mind this is a system that's been running basically as configured presently (save for the dratted optical drive and sound card and those changes were triggered by 10.0 mis-behavior) since SuSE 8.x. It's only with the introduction of 10.0 that things went in the dumper. So... hardware doesn't change, software changes, system goes in the dumper... don't think this is a hardware failure save for 10.0's poor reaction to hardware.
