Comment 6 for bug 954500

Just tested with latest 14.04 image, but it doesn't look good.
System boots fine, but then freezes at the moment you try to open any applications. I managed to switch to tty1 terminal, but then it freezes after few seconds.
when booted with "acpi=off" graphical environment crashes as in previous case, but tty is usable.
I am attaching logs collected with ACPI disabled.
