journalctl -b -1 (see events around Mar 27 22:25:08)

Since the upgrade to kernel 4.10.3 (and continuing on 4.10.4), my gnome-session
consistently fails to return from a lock screen, sometimes showing me a
completely black screen, with only an immobile mouse pointer visible, at other
times the monitor goes off into sleep mode never to return. Logs show that the
kernel "oops" at around this point. I have to finally emergency reboot the
system. journal log attached.
