Nouveau - Jan 2018 - [BUG] Kernel oops when unbinding the graphics card

Hello!

This is the summary of a discussion I had on IRC with Lyude and imirkin_.
When I try to turn off my graphics card, a kernel oops occurs.

Steps to reproduce:
1. Boot the system with no display manager enabled
2. Using SSH, run the following commands:
$ echo 0 | sudo tee /sys/class/vtconsole/vtcon0/bind
$ echo 0 | sudo tee /sys/class/vtconsole/vtcon1/bind
$ echo 1 | sudo tee /sys/class/drm/card0/device/remove

Result:
The integrated display turns black (but not off). Looking the dmesg
reveals that the nouveau driver has come into distress. Here's the
kernel log:

Graphics card: VGA compatible controller: NVIDIA Corporation GK107M
[GeForce GT 750M Mac Edition] (rev a1)
Kernel version: 4.14.13-1-ARCH

Not sure if this is relevant but my laptop also comes with Intel
integrated graphics, which I however disabled (as can be seen in the
dmesg: modprobe.blacklist=i915).

Best Regards,
Samuel
