Calling an electrical noise / timing bug "quantum mechanics" is hyperbole. Otherwise, every EE that touches hardware is a quantum physicist (they're not). EDIT

EDIT: Not trying to diminish the OPs impressive feat of debugging though. Hardware errors can be beastly to diagnose. When wire-wrapping an 8086 computer, I used a spool of wire with occasional (random) breaks that would intermittently open. Worst. Bugs. Ever.
