For some reason your DVD detected as ATA disk device, not ATAPI during
bus reset:

ata4: Identifying devices: 00000001

ata4: New devices: 00000001

It caused further problems:

unknown: FAILURE - ATA_IDENTIFY status=51<READY,DSC,ERROR>
error=4<ABORTED> LBA=0

I have alike ASUS M4N78 PRO board and it looked like working fine when I
last tested. Can you try some other DVD drive on that board? Can you try
to load ahci module to try new CAM-based AHCI driver (be ready to drive
names change to adaX)?
