소프트 잠금 후 네트워크 연결이 끊어졌습니다.

저는 AMD Athlon 3200G를 사용하여 Ubuntu Server 20.04에서 시스템을 실행하고 있으며 최근에 Ryzen 7 1800X로 전환했습니다. 3200G에서는 모든 것이 괜찮으며 아무런 문제도 없습니다.

하지만 새 CPU로 전환한 이후로 매번 몇 시간씩 실행하면 네트워크가 끊어지기 시작합니다.

그래서 Ubuntu Server 20.04를 다시 설치하고 모든 서비스(주로 일부 도커 컨테이너와 도커 내의 역방향 프록시)를 다시 설치했습니다. 하지만 문제는 해결되지 않았고 같은 현상이 반복되었습니다.

Journalctl을 보는 동안 시스템이 실패/연결 끊기기 시작했을 때 소프트 잠금을 언급하는 여러 오류 메시지가 있었고 CPU가 약 20초 동안 멈췄다는 것을 발견했습니다(로그는 끝에 첨부되어 있습니다). 이러한 메시지는 대략 30초마다 기록됩니다.

나는 표준 Linux 사용의 초보자라고 생각하지 않지만 커널에 대한 지식은 상당히 제한되어 있으며 불행히도 오류 메시지를 이해할 수 없었습니다.

누군가 무슨 일이 일어나고 있는지 알고 있거나 이 메시지를 해독하는 데 도움을 줄 수 있을 수도 있습니다. 누구든지 도와주시면 매우 기쁠 것입니다. 미리 감사드립니다!

편집하다: BIOS를 최신 버전으로 업데이트한 후 시스템이 더 오랫동안 안정적이고 결함 없이 실행되는 것 같습니다. 그러나 이제 (다른 CPU에서) 하드 잠금을 유발하는 새로운 문제가 있는 것 같습니다.
