It is a CPU bug. The only solution is to RMA the CPU. Just contact AMD.
They are aware of the issue. All Ryzen CPUs are potentially affected.
Not all Ryzen CPUs are affected, only ones produced until some time
during the spring (week 25 CPUs are said to be good).
It is a good idea to flash the latest BIOS before doing anything else.
Many Ryzen bugs can be worked around with BIOS supplied firmware. The
segfault bug might not have a firmware fix, though.
AMD asks customers to mess around with CPU voltages before RMAing their
CPUs. That's just disrespectful and a little bit silly, IMO.
