I'm on Kubuntu 12.04. I have "noapic acpi=off" in my boot flags. This effects me on two different machines with both the open source FGLRX drivers for my ATI cards.
The exact symptoms are that mouse clicks will sporadically stop working, except that right clicking on some specific application - frequently the KDE taskbar - will make the mouse work normally for one or two clicks.
