어제 새 미니 PC에 Ubuntu를 새로 설치했습니다(Win 10 Pro와 함께 제공됨). 미니 PC는 Belink u55입니다. 이제 화면에 계속해서 많은 오류가 표시되는 문제가 발생했습니다(PC를 화면에 연결하면 SSH에서는 오류가 표시되지 않음). 오류는 다음과 같으며 계속 반복됩니다.

구글에 검색해 보니 같은 문제를 겪고 있는 분들이 많이 보이더라구요수정된 AskUbuntu 주제, SD 카드와 관련이 있는 것 같습니다. 그러나 SD 카드가 연결되어 있지 않으며(둘 중 하나도 사용할 생각이 없음) 파일 내에 " options sdhci debug_quirks=0x40 "을 추가하여 제안된 수정 사항을 시도했지만 슬프게도 이 방법은 작동하지 않았습니다. 누구든지 문제를 더 잘 이해하고 해결하도록 도와줄 수 있습니까? 저는 Linux에 능숙하지 않기 때문에 이 작업을 수행할 만큼 능숙하지 않습니다. 그러나 homeassistand 및 기타 도커 인스턴스를 실행하기 위해 Windows 대신 내 PC에서 Linux를 실행하고 싶습니다. 가능한 수정 사항(나에게는 작동하지 않음)을 제공한 스레드 중 하나에서 누군가 OP에 " lspci -vn " 및 " lsusb "의 출력을 요청했습니다. 따라서 출력이 유용할 수 있다고 생각했습니다. 여기에는 다음과 같은 내용이 있습니다.

기타 유용한 정보:
저는 Ubuntu 18.04.2 LTS를 실행하고 있습니다. 소켓에 SD 카드를 넣을 공간이 아직 남아 있기 때문에 SD 카드가 없는 것 같습니다. 하지만 미니의 내부 작동이 100% 확실하다고 말할 수는 없습니다. PC는 어딘가에 SD를 요구/사용하지 않습니다.
답변1
Beelink BT3-X를 구매했습니다. 동일한 제조사, 동일한 문제입니다. BIOS에서 SD 카드를 완전히 비활성화하여 문제를 "해결"했습니다.
로 이동칩셋->SCC 구성그리고 비활성화SCC eMMC 지원(D28:F0).
하지만 이는 SD 슬롯을 사용할 수 없다는 의미일 뿐입니다.
네... 다행히도 슬롯을 사용할 계획은 없습니다.
