Debian unstable with 4.16-rc2
So i went and installed debian 9.3 and upgraded that to unstable just fine.
Then installed my own build of 4.16-rc2.
This is a headless server so i don't care about audio or graphic support.
I did port the gpio and spi code over to the kernel but I'm not sure if that's working since i don't have anything currently to test and i have like 4 different gpio sysfs entries showing up and those all seem to have more than 40 pins. So i need to do more investigating there.
I'm using the passive metal case, which is awesome. Cpu temp stays around 35c when idle, i haven't stress tested it but during the longish upgrade process, it never got above the 50's. Ambient temperature is about 25c. Cores were hitting the 2+ ghz speeds as advertised.
Network is fine using the vanilla rt driver with the right firmware. Basically same hardware as in a nuc i have that's been running fine for about a year so i'm n not worried about that too much.
Overall, i think it'll make a great little firewall. The case is great. I just wish i didn't need to use thermal pads to allow full contact vs high quality paste but the heat sinks are designed with that pad thickness and i didn't feel like grinding down the screw posts.
