My initial thrill of Ryzens performance for a workstation is now being scarred by random instabilities and crashes when running long-term, on NVMe storage, virtual machines, encoding and BOINC projects when not in use. My feelings from trying to use Ryzen for a workstation - it's not production-ready. Hopefully AMD irons out the kinks in a better BIOS/AGESA/chip revision. There are definitely some I/O issues.
