I've tried it with kernel-4.3.0-0.rc2.git1.1.fc24.x86_64 and at least putting into docking station works fine. (I'll let know whether other problematic actions are problem, but expecting they aren't)
I believe this has been fixed with kernel 4.2.2-300. Would you mind testing and letting me know?
Yes, it works now. Thanks.
Thank you.
