Sorry for the delay. My laptop was away for a while getting repaired.
Apparently water magically appeared on the GPUs and the mobo. Allowing
the repair to cost me instead of the manufacturer. Lovely :-/

Thanks for the replies. I appreciate all the help I can get. Fed up with
windows lol.

Anyway I tried to run apport-collect 1336451. I was unable to do so
because there were missing python modules. At 1st it was pyqt4.qtcore. I
managed to install that. But after that it was pykde4.kdecore and my
Google-fu was not strong enough to find out how to get that.

On the kernel side. I used the kernel from:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.18-vivid/

This is what I did:
- Removed fglrx.
- Rebooted with nomodeset and nolapic. 
- Installed:
                    linux-image-3.18.0-031800-generic_3.18.0-031800.201412071935_amd64.deb
                    linux-headers-3.18.0-031800_3.18.0-031800.201412071935_all.deb
                    linux-headers-3.18.0-031800-generic_3.18.0-031800.201412071935_amd64.deb
- Rebooted with only nomodeset. 

Unfortunately its still the same as before. Somewhere between 10 to 30
seconds after the login screen loads it freezes completely. The mouse
stops moving, its unable to change to a different TTY and I have to
force a shutdown by holding down the power button.

Adding the relevent tags and changing to confirmed as requested.

Title:
  Cannot boot/run ubuntu without acpi=off or nolapic. Freezes otherwise.

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  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

  live CD, the minimal CD and Kubuntu when its installed.
