The fact that it worked means that the combination of that IDE
controller, CD drive, and kernel (and possibly, but unlikely,
specifically that media) results in bad reads while using dma. So if
you're using that controller and drive for FC4, then yes, always use
ide=nodma while installing.
This is a hardware problem, a kernel problem, or both.
