Configure a LED to blink on kernel panic
One of the nice features I remember from Neo Freerunner was how its red LED started to blink fast every time there was a kernel panic, making it easy to notice and to know what happened. There's no such indication on the Librem 5 right now, and since the phone has the compositor running pretty much all the time there's usually no way to know whether there was a kernel panic or some hardware-related hang.
