我在内核 4.13.0-38 中遇到了一个奇怪的问题。
我遇到的问题类似于内核错误参考链接。但不同之处在于我不是在VM中运行。
System details
aravind@comp:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 16.04.4 LTS
Release: 16.04
Codename: xenial
aravind@comp:~$ uname -r
4.13.0-38-generic
Laptop Acer E15 E5-575G-50ZZ
Inter core i5-7200U
Nvidia GeForce 940MX
如果我的系统中安装了英特尔微码，那么我的登录屏幕就会冻结并且无法登录。
如果我删除驱动程序，它可以工作，但日志中会出现错误，
[Firmware Bug]: TSC_DEADLINE disabled due to Errata; please update microcode to version: 0x52 (or later)
如果我检查包裹的详细信息，我发现它有冲突：

现在如何找到冲突的原因并解决此错误？
补充说明：当我从内核版本 4.13.0-28 启动时，同样的配置可以正常工作
