CentOS8Stream报错处理

全新安装的CentOS8Stream(kernel4.18.0-365.el8.x86_64)开机启动报错：
[FAILED]FaildtostartLoadKernelModules.

See'systemctlstatussystemd-modules-load.service'fordetails.
如图：

按提示运行systemctlstatussystemd-modules-load.service，发现是ipmi_si设备不存在导致。错误提示如下：

搜索发现centos论坛中存在讨论帖（见文末），禁用ipmi_sikernelmodule可修复此问题。
故记录解决方法在此，供大家参考：
#查看启动失败服务
systemctl--failed
systemctlstatussystemd-modules-load.service

#配置blacklist

再重启后，此问题消失。
