我的系统运行了一段时间，然后最终变成“只读文件系统”。修复它的唯一方法是重新启动计算机，并希望它允许我这样做fsck而不会陷入某种内核恐慌循环，我只能祈祷下一次重新启动可以解决。就在它发生之前，我收到了一些这样的消息：

Dell XPS 15 - 9560 (Purchased in 2017)
Ubuntu 18.04
到目前为止我已经尝试过：
- 全新安装
- 全新安装其他版本/衍生版的 Ubuntu（19.04、19.10、20.04、衍生版 Pop OS）
- 更换 SSD
注意：有时它们会因内核崩溃而无法安装，而我不清楚原因（我在另一台机器上使用了相同的 USB 密钥）

答案1
AER 错误
您在设备 8086：a11e（一个 PCIe 端口）上遇到了 AER（高级错误报告）可纠正错误。lspci -nn并向lspci -tv我们显示设备 1d.6 是可疑的，但奇怪的是，似乎没有任何东西与它连接。
到目前为止已尝试过的：
- 全新安装
- 全新安装其他版本/衍生版的 Ubuntu（19.04、19.10、20.04、衍生版 Pop OS）
- 更换 SSD
通常我会引用添加一个内核参数来消除 AER 噪声（我可能会稍后这样做），但在这种情况下，我认为我们需要检查一些其他的东西。
记忆
去https://www.memtest86.com/并下载/运行他们的免费记忆测试来测试你的记忆力。至少完成一次所有 4/4 测试以确认记忆力良好。这可能需要几个小时才能完成。
BIOS
笔记：升级 BIOS 前请备份重要文件
您当前拥有 BIOS 1.15.0。当前 BIOS 为 1.18.0，可从以下网址下载这里Ubuntu 的 BIOS 更新过程如下：这里。
