Lenovo 14 iml Touchpad not working in 5.11.0-25-generic (but does in 5.9.0-rc4+-4)

[Gaurav Baghel]

I m having lenovo 14 iml presently running on kernel 5.11.0-25-generic i am using kubuntu
my touch pad is not working here tried many kernels no luck. The only kernel in which it does work was provided by kai-Heng linux-image-5.9.0-rc4+_5.9.0-rc4+-4_amd64.deb it is the only kernel where my touchpad works but the problem is in this kernel virtual box does not work as intended.

Can anyone help me out to figure out how to get this working on any other kernel.

A bit new here if need any new info i will provide.

Can you give me the kai's kernel please? The original download link is broken, I've searching it for several days
