--- Comment #6 from Nathan Whitehorn <nwhitehorn at FreeBSD.org> ---
That output actually looks normal. CPU enumeration happens by repeatedly
descending through the tree -- you will note that the largest value attained by
i gets larger every loop. This breaks down at the last loop where it would have
gotten to CPU 71 but instead stalls. This is confusing to me since it had
already gotten past CPU 66 a few times...

If you back out that specific revision, do things work again? I couldn't quite
follow.
