I just wanted a "vanilla RT kernel" with fedora options but without fedora patches. Hmmm, I just built a 5.6.17-rt10 for Fedora 32 a couple of days ago and it boots on one system I have here (Intel I7 8559U processor, a small NUC mobo in a fanless case). I based it on this .src.rpm (from Koji): kernel-5.6.17-300.fc32.src.rpm I don't remember doing anything different from previous versions (it is now in the Planet CCRMA repo). -- Fernando
