--- Comment #11 from Jason Ekstrand <jason at jlekstrand.net> ---
More specifically, it's post-RA scheduling that's blowing up.  The shader
register allocates on the first try in both cases.  RA must now be creating a
more restrictive allocation which prevents post-RA scheduling from being able
to schedule nicely and/or gives more freedom and post-RA scheduling makes a
hash of things.
