I have total freeze and hot always that the GPU work. distros without GPU support no freeze and cold. All distro with GPU support, no freeze at start, I run glxgears, or glob app 3D bench, and total freeze. I change keyboard,mouse,memory cards,class 4 and 10;8,16 and 32GB(this not work),with swap on and off. I report this problem 4 month ago, but I thought that was a distro issue. Now I test all distro and all freeze. If udoo is cold and run glxgears, freeze and start heating. Distro with GPU support all night on, cold, run glxgears or glob, freeze,or chromium or firefox for few minutes, and freeze.(i think that flash videos or add activate the GPU) . With web browser freeze, at 3 or 10 minutes, but always freeze. I supply power with official cable, and with battery power pack 10000mA with both,9V and 12V. Always freeze. micro-USB, OTG conector on android (2nd for the left), not work, no power if I connect any hardware, pendrive,mouse,keyboard, nothing. I report this problem 5 month ago. Anybody with the same problems? Excuse my bad english.
