The prints are mostly harmless. You're using ATAPICAM, and the ATA
system is fighting with the CAM system over who best knows how to talk
to CDROM devices. It's actually CAM's fault for assuming that all the
world knows what VPD pages are, and it's ATA's fault for lying about the
error recovery behind CAM's back. Blah. There is a unification project
underway to address this. Until then, what you're seeing is harmless.
