[SOLVED] X failing to load nouveau module

Im having an issue when starting X that makes certain programs (like picom or alacritty) to use all of my cpu cores. This happens seemingly randomly after booting and rebooting the system a couple of times seems to fix it untill the next boot, however this is greatly inconvenient.
when looking at X's logs it seems that the issue is being caused by not being able to load nouveau, however when i run lsmod it lists out nouveau, which means it should be loaded

here are some logs/command outputs that might be important:
Xorg log
lsmod
journal -b
modinfo nouveau
dmesg

i think this could be causing the issue though im not very experienced with dmesg so i dont understand what this actually means or how to fix it

[    1.968486] nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 022554 [ PRIVRING ]
 

i hope i've provided sufficient information

Re: [SOLVED] X failing to load nouveau module

Remove xf86-video-intel and try to reproduce. If you don't want to use the nvidia card at all, blacklist nouveau with module_blacklist=nouveau on the kernel parameters and power it off with bbswitch. If you want to use the  nvidia card in any capacity, install the prop drivers instead of nouveau (though by default that will come with increased power usage due to lacking D3 runtime support, check with powertop how much of an impact that is compared to the card being disabled with bbswitch)

Regarding the sub, it would be kernel and HW if anything, but here is fine as well.
