I have almost the same issues, except I run Metacity, so it's not related to compiz, and in my case, the panic can happen at resume but it frequently happens when I (try to) restart or shutdown. It kernel panics with either black screen or text mode, with flashing numlock. Stack trace scrolls off the top, but the symbols clearly indicate it is executing in the wl driver.
