I have Ryzen processor with that UA number.
It have problem with crash under Linux Ubuntu.
This is problem with my hardware or Seg Fault ?
I have comment for my message.
My hardware is brand new it has 2 weeks:
Everthing looks good but under heavy load on Linux Ubuntu 16.04.3 Sometimes it freezes programs sometimes crash the machine.
Computer run on Windows 10 64 home with 2 - 4 VM Linuxes all on stable 16.04 Versions.
My procesor is not overclocked.
