Oh, mine isn't hanging like that. I press enter to boot and then the screen is filled with text saying "invalid kernel opcode".

Yeah I get that if I boot without the kernel cache. This is on an installed system with the prelinkedkenrel built.

Yeah, I wasn't able to install yet.

Does anybody have any suggestions of kernel flags that I could try?

I installed if from El Capitan to make testing a bit easier :thumbup: :lol:

No boot flags will sort it. It's an error in the kernel.

Oh alright. I would try to upgrade my Yosemite installation but I don't want to break my system. :lol:

It's installed on a separate drive. I just ran the OSInstall.mpkg from the packages folder and added in the missing files :) Once the kernel works you'll be able to install correctly :thumbup:

Try this one if you want.

Alright, I'll give this one a shot.

[EDIT]: I used the new kernel this time and instead of it only saying invalid kernel opcode, it was also saying something like this: (It was scrolling really fast, but this is what I was able to gather from it) ".....System won't be able to boot....".
