I made a build with the modified patch. I hope this works fine:

Same here. I was using rt kernels until about 2 years ago, when I was
doing a lot of recording. Since then, I didn't record anything more

on, and so little time :) and I have been using the stock Fedora
kernel. It would be good to test if it is worth.
