How do I troubleshoot my non-working trackpad?

I have a Lenovo Thinkpad Yoga 11e that works perfectly with Fedora 29 running linux kernel 4.19.14-300, but when I upgraded my linux kernel as a part of a normal dnf upgrade and booted into the new kernel the trackpad no longer registers. Touch screen works fine, and I can plug in an external mouse, but it's as if the trackpad is no longer detected.

1.) 4.19.14-300 is now 3rd on my GRUB list of kernels, meaning 1 more upgrade and it will automatically drop that kernel as a boot option. How do I prevent this to buy myself more time to solve the issue? 2.) How would I go about debugging this issue? Usually newer kernels increase hardware support, not the other way around.

Thanks.
