I have been at this for days so I am hoping someone here might be able to shed some light on this issue.  I have multiple miners with a similar issue.  My miners are failing with the error "Voltage read fail. Will exit.".  Below are the last few lines from the kernel log, but I have the full one available if needed.  Thus far, I have tried:
--Resetting it to factory settings
--Flashing the firmware multiple times with multiple version of Bitmain software
--Disconnecting/reconnecting all cables
--Cleaning off the hashing cards and connection bars

I think this is a software issue because I tested all of the cards individually and they all work as expected.  I am able to mine with two cards connected, but not 3.  I also tested a few other 3rd party mining software that allowed me to mine, but I ran into issues with them crashing do to their DevFee not being accepted.  I would be fine leverage a different mining software if there is something decent out there, but so far I have tried Asic.to, Awesome Miner, NiceHash, and VNISH without much luck. 

Is there a different version of Bitmain software to fix this issue or maybe a simple way to disable the voltage discrepancy check?  I reached out to Bitmain support as well, but have not heard back thus far.

Any help would be much appreciated.
