I have installed Iatkos L2 and when it restarts and goes to the apple logo, it shows the Logo with the grey spinning wheel then goes to a black screen and hangs then eventually restarts. I have tried booting with GraphicsEnabler=No and -X -F and cpus=1 etc etc and i have run a -v on it and got the 2 below screen shots.

Could anyone help please as the system was running fine in snowleopard

Let me know what details you need.

The motherboard is a: Asus Z9PE-D8 WS and a Nvidia card out of a Mac Pro (can get model number if required)

Hope you can help
Many thanks
