Hmm.. these look like media presence polling commands from haldaemon. I
have no idea why it's failing on ahci tho. All polling failures I've
seen till now was device dependent, not controller. You can disable
media presence polling using hal-disable-polling /dev/sr0. If you
disabling polling, does the device work correctly? ie. can you read and
record using it?
