Command-power (if CONFIG_XMON is enabled of course).

"P" -> list of processes, may wrap around though, "P<pid>" (all numbers
are in hex in xmon) to see a specific one

"b" -> backtrace current, "b<ksp>" -> bactrace from the stack at <ksp>

"x" -> exit xmon (you may have a stuck cmd key, just press it until it
goes back to normal).
