Thanks, Bisecting actually gave a very weird result. It points to d2137d5af4259f50c19addb8246a186c9ffac325 which is a merge-commit in the x86 tree. Even more weird is that this notebook is the only machine with these symptoms, all my other boxes are fine. During the bisect I tested commits from Yinghai which were good. It seems like the problem appeared with the merge.
