上周我更新了运行 Debian Buster 的笔记本电脑，我收到了警告，但没有适当注意，现在重新启动后，它不会启动到内核 4.19.0.8，但它可以与 4.19.0.6 配合使用。磁盘使用 Luks/LVM 加密。
启动时，我看到这样的消息：
mnc0: unknown controller version (3)
volume group vg-abc not found
cannot process volume group vg-abc
过了一会儿，它启动到 initramfs。
笔记本电脑：戴尔 Latitude E7240
我该如何解决这个启动问题？
根据要求更新 lshw 输出

答案1
让我们面对事实吧：
众所周知，Debian 很稳定，这也是我使用 Debian 的原因。
但让我们面对现实吧，它时不时会出现严重错误，而且很难追踪。如果它与以前的内核一起工作，请认为它是一个错误！真的吗！
我时不时地遇到这样的问题。从来没有任何原因，或者花了几周时间，第一个错误跟踪器才得到第一个带有解释的条目。
Debian 距离完美还很远，所以只需保留旧内核并通过网络搜索不时检查或在上述组件的下一次更新后尝试。
