I have managed to reproduce some lockups, I am suspecting kernel issue. Thermal should not be the cause: because 1. we have performed thermal test in high temperatures 2. other actions are almost safe; I have run some other heavy load programs for a long time, no die. It seems some bugs triggered by the compilation.
Maybe you can try to recompile the kernel with different version/configs. we are going back to work, should be a high priority work for us to resolve.
