We recently bought a Ryzen 7 1800x to build a local server which is in our office. Since the beginning, we got random crashes which occur anytime with no specific reason. However, sometimes we are able to get some verbose log but usually, we got garbage in the syslog. I put in attachment our most recent crash with logs. Unfortunately, we are not able to reproduce the but at all. Therefore, we think it is an issue with our CPU since we observed that the cpu #8 had some issues two times. It would be great if you guys would be able to help us with that issue.
