Hello

I have a similar problem with my laptop:
01:00.0 VGA compatible controller: NVIDIA Corporation GF106GLM [Quadro 2000M]
(rev a1)
kernel: SMP Debian 3.16.7-2 (2014-11-06) x86_64 GNU/Linux

The options nouveau.debug=VBIOS=trace,PDISP=trace,I2C=trace drm.debug=0xe does
make the setup more robust, but I has a crash this morning while expanding the
screen display to an external monitor connected to a dock station.

For what it's worth, I've attached a kern.log generated with the above trace
from the wake up of the machine up to the crash.

Hope this helps
