Hello,

I'm trying to pass trough my second GPU, a STRIX GTX 970. The host,
Kubuntu 15.10, is using a GTX 960. I am unable to keep vfio-pci bound to
the graphics card, that instead is hooked at some point by the nouveau
driver. I am positive that I'm loading the vfio driver correctly, as I
am passing trough also an USB controller and the HD audio controller,
which have no problems. The issue doesn't happen if I use nomodeset in
the kernel arguments.
