cramfs: wrong magic

[petrme]

Live CD boots fine, I didn't notice any problems with applications, but ...

When I try to install edgy eft permanently on my laptop (acer travelmate 3012WTMi) the system is sooner or later frozen and not responding. I try it a few times, last attempt was in "safe graphic mode" (not sure about wording, the second item in the boot menu). This time the system was not frozen, but installer crashed anyway:

We're sorry; the installer crashed. Please file a new bug report at

what went wrong, include the following detail in your bug report, and
attach the files /var/log/syslog and /var/log/partman:

Thanks for your report. This particular error is often due to a faulty CD/DVD disk or drive. 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).

The crash itself is another instance of the kernel oops in bug 67159.
