S17+ Hashrate constantly dropping

Worked fine for first several days. Hashrate drops off. Seems like 1 board is not functioning. A reboot sometimes gets all 3 boards working temporarily. Last 24 hours or so, down to 1 board only it seems.

Attaching a screenshot of Miner Status and Kernel log.

Thanks for any help you can offer.
