The kernel Chris Chiu compiled here:

I (thinkpad e15 gen3 amd) tried the 5.15.1-051501 kernel from mainline test,
but unfortunately there hasn't happened any self-healing in the meantime -

Without having access to the hardware it's quite hard to figure out what
is happening exactly, I wasn't able to reproduce the issue in any other

Title:
Thinkpad E14 Gen2: Kernel panic with trackpad and trackpoint enabled
To manage
well let's be clear here: none of the workarounds suggested in this
thread are fixes, nor are they meant to be, they are workarounds only,
to allow some functionality until the actual fix arrives.
the actual fix will be a new kernel package release that has the

Touchpad is not fully functionalwith @Mark Harfouche's method. You
cannot scroll with two fingers or two finger tap to right click. Not a
fix!

@mark-harfouche, that did the trick for me, thanks.

For those that need to boot and the other methods aren't working, I was
able to boot by adding the following to the grub command line:
```
psmouse.proto=bare
```
as suggested in
https://askubuntu.com/questions/1250841/ubuntu-20-04-elantech-touchpad-
not-working
It should give those working hard
For clarity, I am able to use the touchpad. Honestly, I'm going to be
using the laptop remotely so I can't tell you how smooth it is.
