Involuntary reboot log 10.19

CPU load shot up on machine, frontmost application not responsive to mouse clicks. Command-Option-Escape brings up Force Quit dialog, but it doesn’t work. Mousing over Dock, tooltips still work. Keyboard doesn’t work any more. Closing lid and reopening, everything is working, except keyboard does nothing at lock screen. Hard reset.
