Don't know about chromebook, but on some of my ARM boards > a misbehaving kernel could at least in theory brick the board... I like to live dangerously. Don't imitate everything you see on TV, or read about on lkml. More seriously, that's true if you're running trinity as root, which yes, I usually advise people only do in qemu etc. If you're running it as a regular user and you can brick the board, you might have bigger problems.
