Scary looking stuff while booting

For a couple of months now, I’ve seen dark cyan colored messages while booting and rebooting/shutting down. I am not sure how to read these. If someone can help me out, I will really appreciate it. Below is an image of such text and the latest boot log.

Seems like some firmware is not being able to talk with the kernel. Might be wrong but NVIDIA messing things up.

I see. Is there any way I could fix this? The system is functional, however, sometimes, things just… die randomly and I have to reboot/hard shutdown the computer.
