Hello, I am trying to build the last RT kernel on Fedora. So, I've downloaded linux-5.6.17 and the last rt patch from kernel.org I apply the RT patch to the linux sources. I clone https://src.fedoraproject.org/rpms/kernel.git and checked out to f32 branch I run $ ./build_configs.sh linux-5.6.17 I copy linux-5.6.17.x86_64-fedora.config as .config in the linux-5.6.17 directory. Then, I do a make xconfig I check "General Setup -> Configure standard kernel features (expert users)" to be able to check "Fully preemptible kernel". I save the conf and copy the .config file to be able to build the kernel via a spec file. I used to build regularly the RT kernel via this procedure (the check "General Setup -> Configure standard kernel features (expert users) is new to 5.6) and it was working fine with 5.4 kernels. Now, the installed kernel doesn't boot. Is there something new I am missing to be able to boot the kernel ? Maybe it's the options selected by the fedora script which have a problem. I doesn't apply any patches to the RT kernel. I just wanted a "vanilla RT kernel" with fedora options but without fedora patches. Best regards, YC
