tim-bc, when you staggered turning on the miners one at a time was it only on that circuit/pdu? I have other miners currently running on other circuits and I'm wondering if I need to pull everything and then power them on again one by one.
It seemed to help the first time that all of the dragonmint were restarted, I only lost 1 board. But, after the last time it happened I have done all the steps and I still have 6 boards lost
