I have a NUC6i5SYK (Skylake) running Ubuntu 16.04 server, and I too had some serious problems initially. Installing to the SSD worked without issues, but then I got machine check panics during most boots. After a lot of troubleshooting I was finally able to make the system stable by adding these parameters to the kernel command line: intel_idle.max_cstate=1 i915.enable_rc6=0 After that it has been running without a glitch. I hope it will be as stable as the Mac Mini it replaced. That too had some initial problems however: the first one I bought in 2008 was DOA. Apple replaced it, and the replacement lasted four months before a thunderstorm zapped it. My insurance company replaced that one, and that Mac Mini then ran like a clockwork 24/7 for eight years.
