Spring time is for bugs

Another frustrating evening. On occasion, my processor will not boot if you press the reset button. You can press then button a hundred times and nothing. And yet it never seems to fail when commanded to reset from JTAG.

Since I will be running outdoors soon, I decided it would be a good thing to find this bug. So I sat down to work the issue and after two hours I was unable to reproduce the issue.  Could it be the instrumentation that I added (short GPIO pin pulses) that changed the behaviour?
