I experienced the same issue with Ryzen 5 1600 and Ryzen 7 1700, with AsRock AB350M PRO4 and Asus Prime B350M-A. I try with ubuntu 16.04 normal and hwe kernel, and ubuntu 17.10.
On the system with Asus motherboard, I found a detailed log: Dec 19 06:25:04 am02 kernel: [227622.995187] NMI watchdog: BUG: soft lockup - CPU#0 stuck for 22s!

We're using Ryzen 1800X CPU with X370 Gaming Pro Carbon MB (7A32V1) using latest BIOS available (1.52) We are running Ubuntu 17.04 (amd64), we've tried different kernel version, native one and releases from http://kernel.ubuntu.com/~kernel-ppa/mainline/ too. Tested kernel version: native 17.04 kernel 4.10.15 Issues are the same, we're getting random freeze on the machine.
