Comment 3 for bug 239198

Odd-rationale, I followed the steps you comment and the system behaves exactly the same.
To puntualize, I may say that I installed the system by, firstly starting ubuntu from livecd and then, launching the installation from desktop. The point is that the boot process from livecd also crashed bringing up a shell. I reached to start correctly from livecd by selecting the option 'acpi=off' from the start menu of the livecd (by pressing F6 for advanced options).
Therefore, it may be helpful to somehow include such an entry ('acpi=off') into the normal boot process of the fresh installed system.
I will report any findings on that line..
