I ended up switching from phoenix miner to teamredminer to solve this. Nothing else worked. The only thing I was doing recently was built a custom miner which i ended up not using for Blake2S. Phoenix ran fine for a week after then it lost its mind on a reboot.
Downgrades didnt help. Switching miner to remove previous dag files had worked for me in the past but not this time. I run from a usb flash drive.
This vm fault/gpu fault was causing about one gpu worth of hash power loss. Teamredminer is not having a problem at all.
