What is this? Even when screen locked I've got kernel panic. Why sysrq is turned on by default? How can I trust Ubuntu competence after this kind of stuff.

PrtScn+C means "Perform a system crash. A crashdump will be taken if it is configured."

why you need this in the first place? I think I'll troll some colleagues around. Although screen is locked, I'll just push alt+PrtScn and "c" to create a kernel panic. Cruel? Yes. Who's problem is that? - CANONICAL
