This issue has been fixed in kexec-tools-2.0.28-6.fc41.x86_64 which now depends on makedumpfile.
And I can confirm this issue has been gone with Fedora-Rawhide-20240317.n.0.
Hi Coiby, This is a different issue related to ppc64le makedumpfile filtering error, you are supposed to close below makedumpfile package issue: Bug 2269640 - makedumpfile command not found when building kdump initramfs So I reopen this bug. Thanks Baoquan
Add IBM power experts into this bz in case they happen to know the reason.
