When the system freezes, the caps lock led no longer works with the caps
lock key.  This means the keyboard no longer works, right?  If I were in
ddb, keyboard and caps lock led should still work?

I'll try using serial console tonight (hopefully) and see if any messages
are printed when it freezes.  All I know now is that ping still works,
so the networking code keeps running - but everything else seems dead.
