[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:
