No mouse movement, no keyboard input, the screen output does not change. My computer was using swap space and despite very slow writeout speeds well below what the NVME drive can handle, the computer was unusable. I've captured some vmstat 1 output and top output that I started collecting during the event. (Normally one very long painful period is followed by several shorter periods of uselessness.)
