I was doing my normal, play music, copy files over the lan, do compiles, do email, etc., so I I can't really point you at a reproducer. The graphics system stayed up somewhat but the actual trace I hit scrolled off. This was extracted from the syslog with 'journalctl'. If I encounter it again, I'll see if I can force a kdump.
