Dear Maintainer,
* What led up to the situation?
Updating to the latest kernel. The trackpad starts out fine after a
reboot then gets more and more input lag as time goes on until it ceases to
function.
* What exactly did you do (or not do) that was effective (or
ineffective)? Reverted back to an older kernel. This issue is not
exclusive to debian i had switched to debian stable bookworm a few months ago
because i had this issue on other distros and didn't on debian. With most
recent kernel the issue is now on debian too.
* What was the outcome of this action?
It fixes the issue if i use an older kernel currently using Debian 6.1.119-1
(2024-11-22) and not having the issue, but using the kernel from this month
causes it to occur.
* What outcome did you expect instead? i would expect the newer kernel to
not break my touchpad.
Other info: Device is a Dell Latitude 7400. Other distros i had tried which
also had this issue a few months ago before i switched to debian are, Manjaro,
Mint, Pop, OpenSUSE. Based on the behavior i believe something is causing the
inputs from the trackpad to get backed up. Sometimes the laptop being under
heavy load can cause the issue to worsen more quickly.

I do not have any external devices plugged in so all of these are related to
the built in touchpad i think.
I understand this may be tough to fix without access to the hardware itself,
but im hoping since its a recent issue in debian that something was changed to
cause it and can be easily reverted. If you need any more information please
reach out to me and i will get it for you.
