When connecting to the Thunderbolt 3 Dock, the monitors attach=
ed to it more
often remain black rather than showing a proper image.  Sometimes the Laptop
freezes entirely, other times just one of the two comes up, most of the tim=
e,
they remain black and eventually enter standby.

I'm using a Lenovo P1 featuring a Quadro P1000 Mobile GPU.  An integrated G=
PU
is wired to the internal display as eDP-1.  The Nvidia card exposes an HDMI
port on the laptop.  Plugging a monitor there directly usually works.  Vie =
the
docking station, I get another 3 ports controlled by the Nvidia GPU.  These=
 are
either HDMI or DisplayPort.  I have two monitors for experimentation, a Dell
one and a Lenovo one.

I'm running a Linux 5.2-rc5 kernel and the nouveau driver compiled from a
current checkout of the git repo of Ben Skeggs
(https://github.com/skeggsb/nouveau/tree/f91e915b6a12c281=
aed4401a869881f293b72d4e).
 Most of the time, I'm running with the runpm_fixes of Karol Herbst (that is
the last five revisions from
https:/=
/github.com/karolherbst/nouveau/tree/runpm_fixes).

The output of `grep . /sys/class/drm/card*-*/status` after a start w/o the =
dock
or any display attached is:

/sys/class/drm/card0-eDP-1/status:connected
/sys/class/drm/card1-DP-1/status:disconnected
/sys/class/drm/card1-DP-2/status:disconnected
/sys/class/drm/card1-HDMI-A-1/status:connected
/sys/class/drm/card1-eDP-2/status:disconnected

I'll provide further details of what I did together with the corresponding
kernel logs with tracing enabled in follow-up comments and attachments.
