My laptop is a Clevo P570WM with Intel i7-3970X CPU and 2x AMD Radeon HD 7970M GPU's.
The distro used is Kubuntu 14.04 x64.

Without adding acpi=off or nolapic to the boot flags my laptop freezes a
few moments after getting to the login screen. I have tried various
kernels but the issue persists on all of them. The issue affects the
live CD, the minimal CD and Kubuntu when its installed.
