Issue with lock when switching graphics (nouveau)

[York Possemiers]

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

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.
