I think this might be a problem that at root is due to some CDROM drives
not working well with DMA access to them turned on in the kernel. It seems
to happen with Dells quite a bit.
Have a look at bug 265636, are the symptoms similar?
It would also help to send (to firstname.lastname@example.org) the logfiles from
your install (there is a save logs step in main installer menu) and the
output of (lspci -n; lspci)|sort
