昨天，我在新的迷你电脑上安装了全新的 Ubuntu（它附带了 Win 10 Pro）。迷你电脑是 Belink u55。现在我遇到的问题是，我不断在屏幕上看到很多错误（当我将电脑插入屏幕时，在 SSH 上我看不到它）。错误如下并不断重复：

我在谷歌上搜索了一下，发现很多人都有同样的问题AskUbuntu 主题已修复，这似乎与 SD 卡有关。但是我没有插入 SD 卡（我也不打算使用），我尝试了建议的修复方法，在文件中添加“ options sdhci debug_quirks=0x40 ”，但遗憾的是这没有奏效。有人能帮我更好地理解这个问题并帮助我解决它吗？因为我对 Linux 还不够熟练，无法做到这一点，但是我想在我的 PC 上运行 Linux 而不是 Windows 来运行 homeassistand 和其他 docker 实例。在提供可能修复方法的线程之一（对我不起作用）中，有人向 OP 询问“ lspci -vn ”和“ lsusb ”的输出，所以我想输出可能有用，所以这里是：

其他可能有用的信息：
我正在运行 Ubuntu 18.04.2 LTS - 我认为我没有 SD 卡，因为仍然有空间将 SD 卡放入插槽，但我不能 100% 确定地说迷你电脑的内部运作不需要/在某处使用 SD。
答案1
我买了一台 Beelink BT3-X。制造商相同，问题完全相同。我通过在 BIOS 中完全禁用 SD 卡来“解决”了这个问题。
导航芯片组->SCC配置并禁用SCC eMMC 支持 (D28:F0)。
但这意味着我无法使用 SD 插槽
是的...幸运的是我并不打算使用这个插槽。
