昨天，我在我的新迷你 PC 上安裝了全新的 Ubuntu（它隨 Win 10 Pro 一起提供）。迷你電腦是 Belink u55。現在我遇到了一個問題，我一直在螢幕上看到很多錯誤（當我將電腦插入螢幕時，在 SSH 上我看不到它）。錯誤如下，並且不斷重複：

我在谷歌上查了一下，發現很多人都有同樣的問題AskUbuntu 主題已修復，好像跟SD卡有關係。然而，我沒有插入 SD 卡（我也不打算使用 SD 卡），我嘗試了建議的修復方法，在文件中添加“ options sdhci debug_quirks=0x40 ”，遺憾的是這不起作用。任何人都可以幫助我更好地理解這個問題，也許可以幫助我解決它，因為我對Linux 還不夠熟練，無法做到這一點，但是我想在我的電腦上運行Linux 而不是Windows 來運行homeassistand和其他docker 實例。在提供可能的修復（對我不起作用）的線程之一中，有人向OP詢問“ lspci -vn ”和“ lsusb ”的輸出，所以我認為輸出可能有用，所以這裡是：

其他可能有用的信息：
我正在運行 Ubuntu 18.04.2 LTS - 我認為我沒有 SD 卡，因為仍有空間將 SD 卡放入插槽中，但是我不能 100% 確定 mini 的內部工作原理PC 不需要/在某處使用 SD。
答案1
我有一個 Beelink BT3-X。同一製造商，完全相同的問題。我透過在 BIOS 中完全禁用 SD 卡來「解決」這個問題。
導航晶片組->SCC配置並禁用SCC eMMC 支援 (D28:F0)。
但這只是意味著我無法使用 SD 插槽
是的...幸運的是我不打算使用這個插槽。
