Here is a scratch build package(dmidecode-3.2-3.el7.x86_64.rpm): https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=20324584

Please refer to the test result about bz#1664921(comment#6). I think they are the same issue, therefore, the bz#1664921 is a duplicate bug.

Thanks.

Comment 6 fuguangzhe 2019-05-20 08:42:07 UTC

hi, lijiang

i test this feature on rhel7.7
I could still see "out of spec" with AEP dimms
I check the dmidecode package version is dmidecode-3.2-2.el7.x86_64.rpm

i find you fix it in bug 1664921 with dmidecode dmidecode-3.2-3.el7.x86_64.rpm

So, could you update it to dmidecode-3.2-3.el7.x86_64.rpm for rhel7.7?

Just confirmed that RHEL7.7 has included the fix. Thanks.
