Comment 18 for bug 1970965

a) could somebody point me to some page with the information on how to install and build the official Ubuntu Kernel ? (address of the repository and instructions to build/install it)

I plan to bisect from Mainline Kernel 5.15.4 to Mainline Kernel 5.15.5 to try to catch what is causing the problem

It was suggested to do that with the mainstream kernel (from kernel.org) https://bugzilla.kernel.org/show_bug.cgi?id=215918#c40
but I prefer to start with the kernels from kernel.ubuntu.com , that is what I'm using

b)In parallel, while testing each kernel, I wish to profit and collect more information related to the wi-fi,

which are the logs related to wi-fi modules/driver/function that I can produce ?

(because the output obtained from dmesg didn't provide too much help in this case, or I don't know how to interpret it correctly...)
