The symptom sounds rather like the infamous old AMD64 non-monotonic clock resulting from clocks not being properly synchronised across cores. But I had thought that workarounds in the kernel, JACK, or both had made this a non-issue for most systems installed in the last couple of years. (I am quite sure that a workaround dedicated to solving specifically this problem was merged to JACK trunk quite a number of releases ago, and any contemporary JACK release will have it.) This page: http://www.sound-man.co.uk/linuxaudio/kernel.html refers to the problem. I realise I'm not offering any solution here, just pointing out that your problem sounds the same as this one.
