I've now got over 4 days of uptime with ryzen 1700x on fedora 26 (4.13.9-200) using the rcu_nocbs=0-XX boot option. I feel pretty confident in saying this resolved my issue. Should we be filing a bug report with Fedora as well? Clearly the current kernel configuration isn't compatible with (at least some) Ryzen CPUs.
