TL;DR - 此错误是由于文件系统问题还是硬件问题（卡或笔记本电脑）造成的
所以当我刚刚下班回家时，我的树莓派没有响应。坏消息，因为我家里的 LAN 是 DHCP、DNS 等。
将其连接到电视，插入电源，文件系统错误。显然它由于某种原因重新启动，并且由于错误而无法挂载 root fs。
没问题，关闭电源，取出卡，将其放入我的笔记本电脑中，想着我会很fsck.ext4高兴地运行...
笔记本电脑看不到任何分区。当我检查时，/var/log/syslog我看到 mmc 内容正在加载，但随后似乎出现了与实际块设备之一相关的错误，然后就什么也没有了。
所以...
此内核错误是否是由于我所知的文件系统错误造成的，而我唯一的解决方案是重新映像该卡？
或者这是一个硬件错误，并且驱动程序无法为我的设备正确加载，并且我需要找到其他硬件来修复已知的文件系统错误？
或者这是一个硬件错误，我的卡坏了，圆周率上的 fs 错误只是由于硬件故障而奇怪，我需要一张新卡，当然还要在上面放一个新图像？
笔记本电脑是运行 Mint 19 内核 4.15.x 的旧 Acer
谢谢！

答案1
日志中的最后一个 mmcblk0 错误很大程度上表明是硬件错误。我怀疑你能否重新格式化该卡。
