Thank you for your reply. I agree it’s a dependency / incompatibility issue. I’ve been waiting for another kernel update (via dnf -y update), and today another finally came: 4.11.3-200.fc25.x86_64
This one (a 4.11.x series kernel) works. So while I didn’t solve the issue directly, this update solves it indirectly. =:) I guess the people at Fedora and/or Negativo17 knew about the issue. All is good now. I hope this helps others.
