I can feel that it is very reasonable to set panic_on_warn for the fully
automatic systems because once those warnings happen, the rest of
things can no longer to be trusted, so the goal to kill the first enemy

It could be a good idea for some trees more stable like the mainline,
but for linux-next, I could only dream of set it one day.
