unexpected reboot caused by [Hardware Error]

[Waht]

Hardware Info:
    1th Gen Intel(R) Core(TM) i9-11900K
    MSI MEG Z590 ACE
    GeForce RTX 3090

Operating System Version:
    Ubuntu 20.04.3 LTS

intel-microcode version:
    3.20210608.0ubuntu0.20.04.1

Symptom:
    Unexpected random reboots often happen during periods that no heavy workloads are running. I expected my PC to work as a server 24/7. So, I installed Ubuntu 20 for my PC on Oct 8th, and before Oct 30th, I did not encounter this issue. I can't remember whether I did an upgrade and can't find apt logs back then.

I've tested memory with memtester, and it's all OK.

After I did some research, I suspect it relates to the cpu microcode.

In `dmesg` log I found those errors:
