Comment 9 for bug 626622

I have exactly the same problem but without a laptop (my machine is a desktop). I had to use acpi=off to boot from CD. Impossible to start after installation. I wiil try to use this option again but as mentioned before, this is not a long term solution. I really don't understand how a so severe bug is possible in a release (especially because there was really no problem with previous releases!). Hope for a good solution... coming soon !
