It looks like kernel-6.1.12 has regression at resuming RMI4 devices on SMB bus from hibernate: as a consequence, my Synaptics touchpad is unusable. Dmesg shows:

This used to happen quite often with the kernel v4 line but, AFAIR, disappeared from kernel v5.11 on.

Also, the workaround 

# modprobe -r rmi_smbus
# modprobe  rmi_smbus

doesn't work for me.

What was the last working kernel for you ?

Have you tried adding the kernel parameter:

 "psmouse.synaptics_intertouch=0"

Yeah, it works (now with 6.1.19)! Thanks for the tip -- that passed under my radar, oops ^^

However it looks like we've lost the trackstick's virtual buttons at the top edge... I can do without them (those at the bottom edge are OK), though wonder if that's related.
