I did S3 by rotating the screen down towards the keyboard (--> screen goes black), then back up, and the bug appeared after a minute. Attached is dmesg.

It makes the touchpad unusable : it's not possible to move the mouse anymore, vertical scrolling happens instead. I could not find an action that reliably gets me out of this mode (except reboot !). My workaround for now is to disable two-finger scrolling in "Config / Devices / Mouse & Touchpad", and enable "Edge scrolling" instead.
