In my case, the problem was repeatable with different ShipIt CDs, both "new".
THe install failed in the same place.

The problem is systemic but it is not the physical condition of the media.

More likely the software environment changes at or near the end of the base
install and the new software cannot read the CDs.

In my case Breezy installed and I lost interest in pursuing the problem.

The box in question (SiS AMD) had problems with installing Mandrake 10.1 until
the directive noapic was added. That didn't resolve the problem with hoary.

I know of at least three other machines that had a similar problem, all had
differing software and hardware architectures. These machines would begin or
even complete an install but fail later in the install or after a reboot. In one
case, I installed the OS one one machine, transferred the drive to a second and
stumbled through. In another, I copied the ISO to the disk using a live CD and
then installed from the image on hard disk. In yet another hoary installs but XP
will not.

I've installed Hoary successfully at least 50 times from ShipIt CDs so I too am
inclined to attibute the failures to hardware variance but the problem becomes
manifest when the kernel/module set changes during the install.
