relevant dmesg output

Sorry for the non-descriptive bug title in advance, I'm not sure which parts
of
the logs are worth a bug report, but I'm moderately sure that something in
here
deserves a bug filed.

My machine is a Lenovo P50 with:

    VGA compatible controller: NVIDIA Corporation GM107GLM [Quadro M2000M] (rev
a2)

And mesa version 17.1.8

I connected an external monitor to the HDMI port, and I got black screens for a
few retries.

On an unrelated (maybe not so unrelated?) note, I get reproducible FAULTs on
startup, regardless of any monitor attached or not I believe. I also got some
others on today's log, but that may be just related to the problem above.
The
first two lines below repro even without an external monitor:

    [   75.297725] nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at
690000 [ TIMEOUT ]

Happy to help providing more information, testing, or even trying to contribute
a fix (with some guidance ideally, since I know nothing about the driver's
code
:P).

Thanks a lot in advance.
