I'm here again, after my first comment (Comment 719).

I have Ryzen 5 1600 (UA 1843PGS), and I come to report some news about my case.

I have 2x8GB 2666 Mhz, but in the BIOS Setup, by default, the frequency is set to "AUTO" (2133 Mhz), and in 2019 I had applied it to 2666 Mhz, and I didn't remember this.

My friend warned me about this, that what I did was an "overclocking of RAM", I didn't know that this is an overclocking, so I decided to revert, applying "AUTO" again (2133 Mhz).

Since then... the reboots have stopped, however... the system has continued to freeze, and the logs point only to my NVIDIA GTX 960.

In the BIOS Setup, I disabled the "Global C-State Control", and since then, it has been almost 60 days since there are no more system freezes or reboots, things that happened every day.

Resume:

1. Maintaining RAM frequency in AUTO resolves reboots;
2. Disabling "Global C-State Control" solves my problem with system freezes (log points to NVIDIA).

These two things above solved my problem, and that parameter "processor.max_cstate = 1" in GRUB is no longer needed.
