Hello all!

I'm brand new to the mailing list, and I've encountered an issue with the
microcode_ctl package version 2.1-16 being installed during the CentOS 7.3
upgrade.  It causes my servers to hard stop and they need to be forcibly
powered off and back on again with the power button to continue.

This RedHat thread https://bugzilla.redhat.com/show_bug.cgi?id=1398698 details
the issue, and version 2.1-18 available from Petr Oros' personal section of
RedHat http://people.redhat.com/poros/e6a8cc19d733b1526c2519fbaa1e231d/ is
supposed to fix the issue.  I haven't had a chance to test it yet.

My questions are, who decides what packages are current for CentOS when I
"yum upgrade"?
When can version 2.1-18 be released to avoid this problem?

Thanks in advance!
