我的操作系统出现内核恐慌（它看起来触发了另一个内核转储，kdump？）

我检查了源代码：
https://elixir.bootlin.com/linux/v4.18/source/kernel/sched/core.c#L3287
操作系统应该只在panic_on_warn == 1时恐慌，但我检查了我的操作系统：
sudo sysctl -a | grep -i panic_on
...
kernel.panic_on_warn = 0
答案1
好吧，只是为了确认我的评论，感谢您提供的补充信息：
内核不会因为以下原因而恐慌BUG：原子调度（正如 所预期的那样kernel.panic_on_warn = 0，这不是恐慌的有效理由）但更明显的是由于反复出现硬件内存故障由 MCE 中断处理程序检测到，并且可能是该处理程序中某些致命问题的根源。
