Fix your cable or cdrom drive or controller (maybe torn off/on dma).

You sure it's jumpered correctly? It says its master on the second ide
bus - so there should be nothing else on that bus except maybe another
cdrom. That is, if it is _really_ a cdrom, and not a cdrw, or dvd ...

Move it to the other bus.

Looks like a defective something, but your test does not identify what.
Put another cd in the drive and read it all (use live cd mode).

More or less. Or cable. Or controller. Changing the media and leaving
everything else stable would be the test!

So it looks like a controller problem. Check the dma mode, and change
it.
