Chistopher Penalver, it is hard to say as this is the first release where I can no longer use Catalyst -- I have been using the the binary drivers before this release. I remember my upgrading from 15.04 to 15.10 having a similar looking issue until I reinstalled the binary drivers. I never tried modesetting kernel parameters at that time so I can't say 100% if the error was the same.
