I will look for a possible cause there At this point, to me at least, it seems as if you have a BIOS issue when your system is first powered up. A reboot, without a full power-off, clears the issue. Besides looking at the dmesg file, I would also power-off the system and when you get to the BIOS screen enter what you need to to edit your BIOS and check to see if the DVD has been detected by the BIOS.
