I recently installed Arch linux on my system76 oryx-pro laptop. I'm using nvidia driver. I installed bumblebee and bbswitch however the bbswitch module cannot be load by the kernel and the system gives following message:
[ 1.812163] bbswitch: loading out-of-tree module taints kernel.

My kernel version: 5.16.5-arch1-1
I have tried to black list nvidia module or use suggested "options bbswitch load_state=0" method. None of them worked. bbswitch worked before on this machine but I have no clue what is going on this time. If more system info needed please let me know.
