I had lots of stability issues with mine on Linux kernel 4.15 which I eventually tracked down to the X399 motherboard M2 controller, not the CPU or ram as I had feared. TRIM on my M2 drive had somehow gotten enabled and was causing intermittent crashes everytime it ran as a cron job.

Which SSD was that?
It sounds like your issue was a SSD firmware bug that would have been a problem on any CPU+motherboard platform. It also sounds like your software had really unusual and probably stupid defaults.
Western Digital 1TB M2 nvme
It took something like 4-6 months for a BIOS update to finally bring my TR's RAM to advertised clock speeds (and CPU RAID....). Though, it still had stability problems and overclocking still isn't worth the hassle. Getting the machine to a stable state was very reminiscent of 2008.
Allegedly the second gen threadrippers are going to be much more stable. heh.
