Centos下PCIe Bus Error: severity=Corrected解决方法

网上提供了很多Ubuntu 以下错误信息的解决方法，但是涉及centos的比较少。其实解决方法是一样的，只是加载grub的命令不一样而已

错误信息如下：

解决方法：

1、编辑/etc/default/grub

修改以下内容：

GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet"

   为

GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet splash pci=nomsi"

2、加载grub配置

grub2-mkconfig -o /boot/grub2/grub.cfg

3、重启操作系统后已经没有错误信息了
