RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description RAD team bot copy to z-stream 2019-10-04 14:17:08 UTC 
This bug has been copied from bug #1753541 and has been proposed to be backported to 7.6 z-stream (EUS).
Comment 3 Jeff Bastian 2019-10-09 16:08:19 UTC 
Verified with microcode_ctl-2.1-47.7.el7_6

First do a comparison with rpmdiff against the RHEL-7.8 version (see bug 1753541 for test results) and verify the microcode data are the same (excluding timestamp and documentation differences):

$ rpmdiff microcode_ctl-2.1-47.7.el7_6.x86_64.rpm \
          microcode_ctl-2.1-55.el7.x86_64.rpm |
    grep -v -F -e '..........T' -e '/usr/share/man'
removed     PROVIDES microcode_ctl(x86-64) = 2:2.1-47.7.el7_6
added       PROVIDES microcode_ctl(x86-64) = 2:2.1-55.el7
S.5.......T /usr/sbin/intel-microcode2ucode


Next run a sanity check on a system:

[root@dell-pet3420-01 ~]# rpm -q microcode_ctl
microcode_ctl-2.1-47.7.el7_6.x86_64
