我有一个随机重新启动的Debian 8服务器。 我试图查找从以前的靴子journalctl日志（日志是持久的），但没有发现：
$ journalctl -b -1 -e 试图grep通过所有日志（重新启动，closures，closures，下来，重新启动，恐慌） – 没有什么帮助：
$ grep -rn "reboot" /var/log
我能够在几个GCP和OVH（VPS，专用）节点上重现它。 尽pipe一些具有类似设置的节点工作得很好。

日志里没有什么东西可以触发重启，而且内核恐慌。
我尝试更换/sbin/shutdownbuild议服务器神秘重启，但似乎没有人运行它。
Journalctl日志重新启动后： https ：//pastebin.com/raw/AmkNVs66
请build议如何进一步debugging。
随机重启是由内核恐慌导致的，尽pipe没有日志提示它。 安装和configurationkdump后，我得到了一个堆栈跟踪，帮助我确定问题。 不明显。
