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.

Does it have any other impact aside from console output?

I misread... does it have any other impact aside from log messages?

Hi Kevin,

I dont see any of the dmi facts getting collected and reported in subscription-manager fact --list.

however i see that dmi facts are reported on a normal RHEL 7.5 x86_64 machine.

that's the only thing i could find out.

This bug should probably belong to component python-dmidecode
Comment 6 Jeff Bastian 2018-02-08 19:16:29 UTC 
See bug 1509938 for the python-dmidecode problem.  The module should be trying to read /sys/firmware/dmi/* instead of the raw /dev/mem device because the raw /dev/mem device has been disabled intentionally on aarch64 (see bug 1456956).
Comment 7 Mark Langsdorf 2018-03-29 16:05:57 UTC 
Moving to rhel-alt-7.6
Comment 8 Jeff Bastian 2018-04-12 20:12:27 UTC 
The python-dmidecode bug was CLOSED WONTFIX with the recommendation to migrate to pure dmidecode.  Apparently the python-dmidecode upstream is not responding and it may not be maintained any longer.
Comment 10 Rehana 2021-02-08 15:40:16 UTC 
We will be considering this bug in the future fr RHEL 9 https://issues.redhat.com/browse/RHELPLAN-46044 . Hence closing this bug on RHEL 7 .

thanks,
Rehana
