Ubuntu 서버 20.04가 자주 자동으로 다시 시작됩니다.

내 우분투 서버 20.04는 종종 자동으로 다시 시작됩니다 /var/log/messages.

ERST: Error Record Serialization Table (ERST) support is initialized.
RAS: Correctable Errors collector initialized.

그래서 grub에서 acpi를 비활성화했는데 CPU 코어 수가 1개밖에 없어서 acpi를 비활성화할 수 없는데, acpi를 비활성화하지 않으면 우분투 서버 20.04가 자동으로 자주 재시작하게 됩니다. 그래서 내가 무엇을 할 수 있니? 도와주세요
