It looks like the patch backported for https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1508609 is not quite enough to fix this issue on pre-4.1 kernels. Those kernels also need https://github.com/torvalds/linux/commit/00df35f991914db6b8bde8cf09808e19a9cffc3d (or in general, must call cpu_notify before smpboot_unpark_threads).
