This says your kernel is tainted, are you using any proprietary drivers?

Make sure you try the latest kernel from rawhide:

sudo yum install fedora-release-rawhide
sudo yum update kernel --enablerepo=rawhide

If you can still reproduce there, please file a bug against the kernel
component in fedora. Please CC me on the bug report, and report the bug number
here after filing so anyone else on the mailing list can follow along there.

Thanks,
Cole
