[Bug 1933377] Re: Thinkpad T14 touchpad movement suddenly not working

Could you run apport-collect 1933377 to collect logs for your bug
report? I'll have more information about the interrupts.

And please download and install the latest amd64/build generic deb files
in https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.13-rc7/ (see
section "How do I install an upstream kernel?" in
https://wiki.ubuntu.com/Kernel/MainlineBuilds) and reboot, let us know
if the problem can still be reproduced and paste your "uname -a" command
output in a terminal (ctrl+alt+t) here.

Title:
Thinkpad T14 touchpad movement suddenly not working

Status in linux package in Ubuntu:
New

Bug description:
I have a thinkpad T14 (20UE) with a Synaptics touchpad. The touchpad
clicks show up in evtest but don't actually work (or show up in
libinput debug-events) and movement doesn't work at all. I've tried
setting xorg to use the synaptics driver and libinput driver with no
effect. I'm using kernel 5.10.0-7-amd64.

I've attached logs as
https://wiki.ubuntu.com/DebuggingTouchpadDetection describes, as well
as the one from libinput.
