I was having the same issues, was on 1.5 fw and had the exact same freezing. Tried the master but no luck, then I did the dumb thing and tried doing an install of the master and it bricked it, I was forced to reflash 1.5 and this time ran the master from the start and it worked! I just want to say how amazing the interface is, I was not sure it I wanted to keep gmenux2 or switch but after using it I am hooked! Gmenux2 looks antiquated in comparison. Any way we can OC further than 624mhz? I had a stable OC at 642 using gxmenux2. Please keep up the amazing work with this, I love it.
