Journal Errors - i915 intel integrated graphics not working

These are the following errors I get during a normal reboot cycle:

-- Reboot --

-- Reboot --

The one that concerns me the most is the i915 specific error as that has a significant impedance on the startup time of my machine (roughly adding 10-20 seconds). It feels like its trying to startup the display manager and it fails so it returns, switches to the nvidia card and it works. I've checked the wiki and also a couple different community hubs - still haven't found a conclusive answer. The closest I've gotten to it is a few threads from a couple years ago but it mentions that its a kernel side problem. I would imagine that those should be fixed by now?

I also occasionally get an additional error:

Aug 30 23:16:11 faetablet kernel: [drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe A (start=28388 end=28389) 

I've read the following can be fixed by adding a kernel parameter - i915.enable_psr=0. I haven't been able to test conclusively if this fixes that error or not since I only get it sometimes (though I haven't gotten it in the last 2-3 boot cycles since I added the kernel parameter).


Thanks for your help!
