> Turns out it was the CPU and how crappy AMD handle C-states that save energy
From my experience, Intel is no better.
I have a 4 year old laptop with an Intel CPU that has the same problem, it was never fixed by Intel. [see EDIT]
For the first 3 years of use I just accepted the fact that my laptop would randomly freeze and I would have to reboot it.
One day, I got sick of it and started digging into forums until I found a way to avoid the specific c-state (by modifying kernel boot parameters) that caused the issue.

EDIT: Apparently, it's getting fixed now. Just 5 years late, issue was reported in 2015 https://bugzilla.kernel.org/show_bug.cgi?id=109051
