There is a bug in the kernel which causes the media check to say some CDs are bad
when they are not, on some systems. To do a successful media check, do the
following:
- At the installer prompt, type:
linux mediacheck ide=nodma
- Run the media check on your CDs/DVD.
- Reboot, and run the installer normally.
Note that sometimes mediacheck will report that only some
CDs are bad, but this will still fix that problem. (Thanks to Tony
Nelson for reminding me of that!)
