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).

Comment 1 Xiaoqing Wei 2014-02-25 08:16:56 UTC 
not major incident observed yet(kernel panic)
Comment 2 Anton Arapov 2014-02-25 08:49:13 UTC 
moving to kernel. microcode_ctl doesn't have "loader" function in rhel7.
Comment 7 Anton Arapov 2014-02-25 10:48:16 UTC 
You see this message because NO amd microcode available at all. I will work on the upstream code to make the message more informative.

Comment 8 Johnny Hughes 2014-10-30 12:05:11 UTC 
Note:  it should be against the rules to close a public bug as a duplicate IF the original bug is not open to the public.  The community also needs to see fixes.
Comment 9 Muhammad Aizuddin 2015-04-20 11:34:22 UTC 
i would totally agree with Johnny, community also need to see fixes.
Comment 10 Akemi Yagi 2015-06-10 21:25:15 UTC 
If the "other" bug cannot be opened, could someone at RH update the status here? 

Is the plan to update the displayed information but not to actually include amd microcode?
Comment 11 Mauro Mozzarelli 2015-09-29 08:20:34 UTC 
bug 866700 is not accessible, the issue persists and the assignee provided indication that the issue might not be addressed correctly thus I will add the following information:

The directory /lib/firmware/amd-ucode containing the following files:
/lib/firmware/amd-ucode/microcode_amd.bin
/lib/firmware/amd-ucode/microcode_amd_fam15h.bin

was omitted from microcode_ctl-2.1-10.el7.x86_64 package.

The temporary solution is to copy the relevant directory from package
microcode_ctl-1.17-20.el6.x86_64 distributed with RHEL 6.6.

Anton Arapov is thus wrong since the microcode IS AVAILABLE, but not packaged in microcode_ctl for RHEL7.

The fix should consist of including the relevant directory and files in the upstream RHEL7 microcode_ctl package.

I also request Anton to clarify on the status given that bug 866700 cannot be accessed. Thank you.
Comment 12 Mark Willert 2015-10-05 12:40:17 UTC 
Got the same with an AMD A4-5000, but the missing file is microcode_amd_fam16h.bin

The Microcode is also available from AMD:

http://www.amd64.org/microcode.html

The newest file includes:

- microcode_amd.bin
- microcode_amd_fam15h.bin
- microcode_amd_fam16h.bin

which solve this error message if copied to /lib/firmware/amd-ucode

So this can be solved by packaging the manufactorer's files.
Comment 13 Mauro Mozzarelli 2015-10-05 17:50:43 UTC 
Mark,

We know the microcode files are available both from AMD and previous CentOS 6 release packages. 

What is not clear yet is if we are supposed to update the firmware files manually every time or if they will be packaged as expected in the next kernel-firmware package to correct the issue.

Thus I do not consider this issue resolved. I proposed too to re-open this bug until either the files are correctly packaged in kernel-firmware or we have an acknowledgement that they will.

Mauro.
Comment 14 Mark Willert 2015-10-05 18:20:14 UTC 
Mauro,

the point was just that CentOS 6 does not pack all available microcode patches, so taking directly from AMD looks like the better choice.
Comment 15 Mauro Mozzarelli 2015-10-05 19:39:38 UTC 
It should and it does not take a great deal to copy the AMD firmware in the package.
Comment 16 Kevin Zhang 2015-12-20 04:16:19 UTC 
Can confirm this issue on a system with an Athlon II X4 635 (Propus). Downloading and copying latest microcode files from AMD website seems to improve system stability as well as speed. Hopefully these files get rolled into the next kernel-firmware RPM, as they should be...
