I get the one testing mbs with Intel new general processor( Comet Lake ) Intel(R) Celeron(R) G5900TE CPU @ 3.00GHz
when installing the Centos 7.7 1908 DVD and install some packages. we find the message and dmesg will have mce error/warning.
Due to Centos 7.7 yum repolist mcelog only support 144 version.

I try to update the MCElog 170 version by github can solve decoding architectural errors issue.
[root@localhost ~]# mcelog --version

But, below kernel warning I cannot fix, and try to update to kernel 5.7.4 result is the same, I will share to the BIOS team to check it.

may we need Team help to advise and support if the problem can solve on Kernel update in the future?
Intel Comet Lake MCE error
Re: Intel Comet Lake MCE error
This isn't an mce error, it's just a warning spit out during the setup of the mce driver: your firmware (bios) is buggy. Because the kernel detected this and worked around it, no further action is required.
Besides: 7.7 is dead by now and totaly unsupported.
