I just tried the "console" workaround, which worked perfectly. Back to normal.
If it happens again, I will try the "suspend" workaround.

everything works fine.

touchpad and releasing it should be like a mouse click) -- simply

I've found a workaround: put the system into standby mode, and upon the
wakeup, the touchpad is fully working again.

It just happened right now. I've saved dmesg output and the X's log.
(Attaching them.)
There are no nvec messages in dmesg. But there are two "ec" messages.
Are they important?
I've checked once again the behavior of the touchpad when this happens:

At least, in the *tail* of overall dmesg that I have attached (which is
some while after this issue occured) there are no nvec-related messages.
But maybe the moment when the touchpad stopped working was already cut
off in dmesg.
There are quite a lot of "page allocation failure" messages there. C

@marvin24: thanks for your comment!
And what does it mean if there are nvec-related messages in dmesg?
I don't understand what nvec is, and what its relation to the touchpad
is.

Perhaps, you'll find something in my dmesg.
It happened about an hour before I'm submitting this bug report (right
