Hello,

I did a very dumb thing and upgraded my 13.85 auto-frequency miner to Bitmains latest firmware.  Of course, as soon as the miner rebooted, it only had 2 boards hashing.  Did a little digging around and see that in the logs in mentioned that chains[5][6][7] have low pic voltage.  It then says that it is using backup chain_voltage - however, it is still reading one of my boards as having 0 asic.  At the end of the log, I believe it just ignores this last board and runs with the two it finds chips on.

I know this is not a board issue as the fucker was running great right up until I flashed the new firmware.  Errr... Help!
