Comment 4 for bug 104600

Judging from all the squashfs errors in your syslog, it looks like the root cause of this was a problem reading from the CD. This is generally due to a faulty CD/DVD disk or drive, 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).

However, the particular violence of the crash here is also bug 69470, and will be fixed in the final Feisty release.
