关于此告警，HPE官网已发布过技术公告，为Intel CPU微码问题，需要升级BIOS版本到2.42以上：

Intel has released new specification updates to their Xeon Scalable Processors (Skylake) and Second Generation Xeon Scalable Processors (Cascade Lake) in January 2021 that detail two new errata which are resolved, except for the HPE ProLiant e910/e910t Server Blade, by applying the System ROM version 2.42.

升级BIOS到2.42以上，以修复此问题。
