Please don't top-post; reply inline with appropriate context instead. Replying
inline allows readers to follow the conversation flow.

Again, as I repeat, please test mainline kernel first. Since you're about
to compile your own kernel, there is a kernel documentation on it [1]. Or
you can follow Rocky Linux's guide ([2]) (as it is based on RedHat).

Thanks.
