Public bug reported: My touchpad (Lenovo Ideapad Slim 7, Intel version) was working fine until I woke the laptop one time and it stopped working. It did not appear in /proc/bus/input/devices.
Restarting did not help. However, after restarting into 5.8.0-25 the touchpad worked again (devices file attached). Then restarting again into 5.8.0-44 everything was working.
