오류: 비휘발성 변수 저장소가 거의 가득 찼습니다. 어떤 efvar를 삭제할 수 있나요?

Thinkpad W530과 ubuntu 21.10을 사용하면서 최근 컴퓨터가 부팅되지 않고 오류 메시지가 표시되는 문제가 발생했습니다.

Error: The Non-Volatile Variable Storage is About Full

몇 번 재부팅을 시도하고 BIOS에서 부팅 항목을 삭제한 후 성공적으로 재부팅했습니다. 그런 다음 몇 가지 조사를 수행한 결과 이것이 설명된 내용과 관련이 있을 수 있음을 발견했습니다.여기. 그런 다음 링크에 표시된 대로 tlp ppa를 통해 acpi-call-dkms를 버전 1.2.2로 업그레이드했습니다.

다음으로 efivars를 제거하고 싶지만 *dumb*이와 같은 것을 찾지 못했습니다.

그래서 삭제 후 오류가 다시 나타나지 않도록 내 efivar 중 어느 것을 안전하게 삭제할 수 있는지 묻고 싶습니다.

이는 다음의 출력입니다.sudo ls /sys/firmware/efi/efivars/
