Subject: MCE reports errors that can't be verified
Date: Mon, 29 Oct 2018 11:45:04 +0100 [thread overview]
Message-ID: <6ccf5413-ce2a-bbb9-0203-b0cc9fe2e641@profihost.ag> (raw)
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?
