Comment 6 for bug 87053

Exit code -11 is a segmentation fault; the only real way that can happen in this particular context is if there's been a problem reading from the CD. This is generally due to a faulty CD/DVD disk or drive, or possibly faulty memory, rather than being an installer bug as such. 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). Also try doing a memory test from the CD boot menu.
