Hi,

Perhaps watching the output of some input event tools could help
gather some clues to eventually get it nailed down?

Some candidates:

evtest - utility to monitor Linux input device events
input-utils - utilities for the input layer of the Linux kernel
xinput - Runtime configuration and test of XInput devices

And what do /proc/interrupts counts say? Does PS/2 (i8042) generate events?

while :; do clear; cat /proc/interrupts; sleep 1; done

HTH [shot in the dark],
