Can you also run something with "DRI_PRIME=1" (to use the NVIDIA GPU) and see
if you get any additional dmesg output from nouveau?

I've been looking at an older GM108 trace to try and add support for it (I
don't have the hw myself), and see some things in that that need fixing and
should cause errors from the hw if the graphics engine is used.

Thanks,
Ben.
