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?
