Recently after trying to install Gnome and Ubuntu Gnome i get the kernel Not Tainted on vop2:
[ 9.967723] WARNING: CPU: 7 PID: 540 at drivers/gpu/drm/rockchip/rockchip_drm_vop2.c:3288 vop2_crtc_load_lut+0x770/0x948

According to some kernel doc:
title: Rockchip SoC display controller (VOP2)
description:
VOP2 (Video Output Processor v2) is the display controller for the Rockchip
series of SoCs which transfers the image data from a video memory
buffer to an external LCD interface.
@amazingfate, @icecream95
Is this a known issue or there is a patch to fix this?
This happens on rkr3.6.
Edit:
Removing Ubuntu-Desktop fixed the issue.
Running Gnome Wayland apparently no problem with software rendering.
