Hi,
I am experiencing a similar problem as Gianluigi on my Lenovo X1 Extreme Gen 2
running Debian Testing with Gnome where touchpad click is non-responsive while
running kernel 5.10.
There is no response whatsoever to clicking the touchpad, and the pointer does
not respond when one finger taps and holds or clicks and holds and another
finger drags across the touch pad.
The kernel packages and versions used:
5.9.0-5-amd64 #1 SMP Debian 5.9.15-1 (2020-12-17)
5.10.0-1-amd64 #1 SMP Debian 5.10.4-1 (2020-12-31)

I similarly have a small hang on shutdown with the error:

There is no noticeable significant change in behavior or log messages when
booting with psmouse.synaptics_intertouch=1.
With psmouse.synaptics_intertouch=0 the touchpad seems to work as expected.
