The solution to the error: nouveau failed to create kernel channel
The error
nouveau 0000:01:00.0: DRM: failed to create kernel channel, -22
Normally occurs due to a driver problem with Nvidia cards when booting a Linux / Debian machine.
The troubleshooting is relatively easy to do by first creating the following file:
vi /etc/modprobe.d/blacklist-nouveau.conf
INSERT KEY
blacklist nouveau
options nouveau modeset=0
ESC-BUTTON
:wq
After that, we update the core and restart the computer:
update-initramfs -u
reboot
