DSDT/ Hotpatches: Yes I know usually I do this after I can boot the machine succesfully.
My problem is, with the EFI i uploaded i can easily boot and install the machine. When I try to boot into the system the first time, verbose mode runs through until the graphics unit gets activated, then i just see the apple sign and boot stops.
So i guess it is graphics related but i can´t figure out the problem. Moreover once in a while the machine boots flawlessly with full acceleration.
