We've now seen this idle lockup with a Ryzen Pro 1700X based system running current Fedora 27. As with my Fedora 27 system, it is avoided by using 'rcu_nocbs=0-15 processor.max_cstate=5'. The hardware is an Asus Prime Z370-Pro motherboard, EVGA SuperNova G3 650W PSU, 2x 8GB Kingston ECC RAM, and an nVidia graphics card.

(It's disappointing but not surprising that the Ryzen Pro doesn't seem to fix this.)
