This looks like either a physical CD problem or a known SqushFS bug which has since been fixed. It may help to clean the CD/DVD, to burn the CD/DVD at a lower speed, or to clean the CD/DVD drive lens (cleaning kits are often available from electronics suppliers).
I'm closing this bug, but if you see the same problem with a copy of 6.10 final after having checked your drive, please re-open.
