I'm not sure if this is an NHM issue or an NVML/NVIDIA issue but wanted to make you aware of it. Sometimes after running for a while, the GPU status goes away. This has been going on for a long time. Today, however, I noticed something new. I'm still on v1.9.1.5 until after the platform switch but I imagine the issue persists. The power usage shown in GUI is over 100x what the miner says it is. I don't think this is related to the power settings issue. Thanks and take care!

@jwesolo thanks for reaching out. It is indeed a bug in plugin implementation and will be fixed asap.
Stay tuned for the new releases.
commit fixes this issue (T-Rex, NBMiner and GMiner have this issue).
Will close issue on next release or on next miner plugins update.
