dmesg.display_port_problem.4.2.3-300.fc23.x86_64

I get a flood of kernel events from nouveau when connecting and disconnecting
my 2nd display via the display port cable.

Events start with this:

nouveau E[   PDISP][0000:01:00.0] INVALID_VALUE [UNK84] chid 0 mthd 0x0700 data
0x00052002


modinfo nouveau -n
/lib/modules/4.2.3-300.fc23.x86_64/kernel/drivers/gpu/drm/nouveau/nouveau.ko.xz

lspci -v | grep -i vga
01:00.0 VGA compatible controller: NVIDIA Corporation G92GLM [Quadro FX 2800M]
(rev a2) (prog-if 00 [VGA controller])

Errors come and go with connection/disconnection of the Display Port cable.  So
long as I stay running in init 3, the primary laptop LCD continues to function.
 Once I go init 5, X appears to start, and then just hangs.

I've attached dmesg output for boot-up, when I connect the display port, and
when I disconnect the display port.

Please let me know if I can help in any way.
