Hy Malamama.
I had the same issue when another forum fellow brought to me an S9 that was behaving wierd.
His machine was running full 14Th for a while, then it would start to oscilate hash power very much, and finally one hashboard would stop.

After flashing the latest firmware from bitmains's site, first the miner showed the same issue like yours, but after about 10 -15 minutes it would start hashing and the error was gone...

So you could let run for a while and see if the miner starts hashing.

BTW: after this firmware flash, the miner stays rocksolid at 14Th according to him.
