--- Comment #1 from Mark Johnston <markj at FreeBSD.org> ---
Hmm, I can't even boot a non-SMP amd64 kernel on head; we panic when adding a
thread. I guess this is some fallout from the recent scheduler locking
optimizations. That said, I can't quite see the issue from looking at the
DTrace code. Which revision are you running? Out of curiosity, why are you
using a non-SMP kernel?
