With origin pointing to git.git, I attempted this:

  git bisect start
  git rev-list --first-parent --boundary origin..origin/pu |
    sed -ne s/-//p | xargs git bisect good
  git bisect bad origin/pu

and it starts bisecting among the 50-something first-parent commits 
between origin and origin/pu.
