hi, all!

I'm using nvOC for a while and today got some rigs broken, tried to see what's wrong and got this error when launching nvidia-smi: "Failed to initialize NVML: Driver/library version mismatch". This happened to every nvidia rig that I tried to reboot. Never touched the drivers in nvOC distro, so I'm confused how this could happen... Does anyone have ideas? Is there any kind of autoupdater which could change something after reboot? How to disable it and make everything working again?
