I've temporarily fixed my problem by grounding my PinePower.
No need to take it apart. I simply plugged an additional USB cable into the PinePower, and connected the 0 Volt wire of it to ground.
This removed the 92Vac I was seeing on the Pinecil, and it doesn't appear to crash and reboot now.
It is also a lot safer when soldering ESD sensitive components.
Personally I would have preferred the soldering iron tip to have a 1M Ohm bleed resistor to ground, as that would be the safest when working on ESD sensitive components, but this still resulted in around 50Vac at the tip and occasional crashes and reboots. I guess the Y-class capacitors in the PinePower are leaking around 50uA of current onto the 0 Volt supply rail and the Pinecil is very sensitive to supply disturbances.
