I don't think spacemacs is going to solve your problem. I'm using it, and it freezes/crashes at least 5 times a day for me. 

What exactly do you mean by "system keeps freezing to report types"? Does emacs become non-responsive or your entire system? For how long? After which keystroke - c-c c-t or c-c c-i? How big is your Haskell project?
