Adding to the confusion here:

I'm running a Ryzen 1700 on Asus PRIME B350-PLUS motherboard and on BIOS version 4011 I have the "Power Supply Idle Control" option and I have changed it from "Auto" to "Low Current Idle" a week or so ago and after that I have had zero lockups.

According to this bug report disabling C6 states *or* setting that option to "Typical Current Idle" should work and "Auto" should mean "Low Current Idle" hence it should not have made any difference. zenstates.py shows C6 enabled for both package and core.

Unless the Ubuntu 18.04 kernel 4.15.0-*-generic got an off-tree patch applied somewhere in-between my reboots I'm confused and relieved at the same time.
