Got a really weird error screen when I start installation/boot into Yosemite

[cosmopath 0]

What on earth did I do? I installed Yosemite, restarted the computer, selected the place I installed it on in Darwin, and I get this error:

If I try re-installing it I get the same error.

Any help is appreciated!!

I have a Haswell i5-4210U CPU btw. I already tried /haswell and /cpus=1.

Its a kernel panic, after you install yosemite make sure you replace with the proper Yosemite Version kernel for haswell on your installed hdd in S/L/Kernels, then boot with -f and see what happens
