最近我的系统开始表现不正常并且出现了一些崩溃。目前我正在运行：
ola@station:~$ uname -a
Linux thinkstation 4.9.0-8-amd64 #1 SMP Debian 4.9.110-3+deb9u4 (2018-08-21) x86_64 GNU/Linux
在过去的几周里，我遇到了严重的内核崩溃。今天早上最后一篇：
ola@station:~$ last | head -n 50

reboot system boot 4.9.0-8-amd64 Thu Aug 30 17:49 - 20:43 (02:53)
然后我正在查看kern.log显示以下输出：
