Hello, For a fuloong (loongson2f) I had two configs, one booted and the other not, on a linux 3.8. I narrowed down the difference to enabling CONFIG_FTRACE. Enabling CONFIG_FTRACE makes the kernel not load at all; it even does not print any early printk to the serial port. Do you agree there is a problem with FTRACE? Maybe it is solved already in the mips git branch? Regards, Lluís.
