I'm assuming the PDB issue was with one of the voltage regulator outputs? I recall 330 having a PDB issue in 2011 or 2012 (I think) where the 24V regulator would have semi-random very short duration dropouts that would cause their cRio to reset.

Fortunately this issue will go away in 2015; the new control system not only uses straight battery power for the roboRio (operates natively down to ~4.5V), but also the new PDB has no regulators whatsoever (an separate power converter module provides regulated 5V and 12V for radio/custom circuits), making for easier replacement of just the regulator component.
