--- Comment #11 from Stuart Longland <stuartl at longlandclan.yi.org> ---
Now running a kernel built from the Nouveau git tree at this commit:

commit ff4c0d5213b015e60aa87c1352604f10ba9c3e12

    drm/nouveau/nouveau: Do not BUG_ON(!spin_is_locked()) on UP

    On !SMP systems spinlocks do not exist. Thus checking of they
    are active will always fail.

    Use
      assert_spin_locked(lock);
    instead of
      BUG_ON(!spin_is_locked(lock));
    to not BUG() on all UP systems.

I've been tinkering in OpenSCAD for a while and it has not yet crashed.  Maybe
this weekend I'll try stock kernel 3.18.0-rc4 then bisect until we figure out
what patches fix it and try cherry-picking those.
