No, I think we're good. I suspect this is a different issue. Do you have lockdep enabled, along with mutex and spinlock debugging etc? That might help pinpoint what triggers this.
But I think the fact that you are apparently not able to get the list corruption is a good sign. Of course, it might just be harder to trigger, and these things could all be a sign of a different bug, but my gut feel is that we did fix something, and you are just damn good at stressing the new code. Kudos.
