SubjectMCE reports errors that can't be verified
Date
Hello,

We currently have several servers reporting faulty memory through MCE.

Example dmesg output:

[Mi Aug 22 13:54:47 2018] mce: [Hardware Error]: Machine check events logged

Normally we verify those errors by checking IPMIs event log, but no
errors are showing there.

Neither IPMI nor ras-mc-ctl report any errors.

We encountered this problem running Kernel 4.12.0 based on openSUSE
SLE15 on commit a906b62b3f80679eac4f38373492a871c5f3568e.

Is this an MCE Kernel bug?
