解决方案为：

1. 编辑/etc/default/grub

修改以下内容：

GRUB_CMDLINE_LINUX=“crashkernel=auto spectre_v2=retpoline rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet”

为

GRUB_CMDLINE_LINUX=“crashkernel=auto spectre_v2=retpoline rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet splash pci=nomsi”

1. 加载grub配置

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

1. 重启电脑reboot。
