It might be a patch added by one of Fedora kernel developers. CC'ing
fedora-kernel
You can test this with a non-patched kernel from Fedora kernel
source rpm using the "--with vanilla" option to rpmbuild.
If kernel-vanilla works, the problem is in a Fedora patch.
If it still does not work, the problem may be caused by some
kernel configuration options.
