So having conferred with Karol Herbst in #nouveau on freenode, when attempting to run $ DRI_PRIME=1 glxinfo, the following stacktrace turns up in dmesg https://gist.githubusercontent.com/karolherbst/cd8292689959417a0111/raw/d583...

Running kernel 4.4.0-0.rc3.git1.1.fc24.x86_64 (Fedora Rawhide) I'm not really sure where to direct this, I was advised that I should post this here. If any more information is required, I am happy to provide.
