--- Comment #28 from J <rhbugzilla at vontersch.com> ---
I have a similar problem, but with a different card.  I believe my errors start
the same way as the original poster.

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])

I'm using a laptop (dell m6500) and get a bunch of nouveau errors printed when
I connect my 2nd display via the display port.  So long as I stay running in
init 3, the primary laptop LCD continues to function, but once I go init 5, X
appears to start, and then just hangs.

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

Please let me know if I've posted to the wrong bug or can help in any way.
