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!
