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.

Red Hat Product Errata RHBA-2016:2171 0 normal SHIPPED_LIVE kmod bug fix and enhancement update 2016-11-03 13:16:08 UTC

Description Thomas Huth 2016-03-22 14:49:53 UTC 
Description of problem:
When compiling the latest upstream kernel (4.5.0) with the current tools from RHEL 7.3, there are a lot of annoying messages like this while doing "make modules_install":

depmod: WARNING: /lib/modules/4.5.0-thuth/kernel/drivers/media/radio/tea575x.ko needs unknown symbol .TOC.
depmod: WARNING: /lib/modules/4.5.0-thuth/kernel/drivers/power/smb347-charger.ko needs unknown symbol .TOC.
depmod: WARNING: /lib/modules/4.5.0-thuth/kernel/drivers/hwmon/hwmon-vid.ko needs unknown symbol .TOC.
depmod: WARNING: /lib/modules/4.5.0-thuth/kernel/drivers/hwmon/w83792d.ko needs unknown symbol .TOC.
depmod: WARNING: /lib/modules/4.5.0-thuth/kernel/drivers/hwmon/w83793.ko needs unknown symbol .TOC.
depmod: WARNING: /lib/modules/4.5.0-thuth/kernel/drivers/hwmon/w83795.ko needs unknown symbol .TOC.
...

Version-Release number of selected component (if applicable):
$ rpm -qf /usr/sbin/depmod 
kmod-20-6.el7.ppc64le

How reproducible:
100%

Steps to Reproduce:
1. Compile the latest kernel sources on a ppc64le system
2. Run "make modules_install" to install the modules.

Actual results:
A "... needs unknown symbol .TOC." message for each kernel module that is installed.

Expected results:
No such annoying messages.

Additional info:
A patch has apparently been suggested here:

Comment 2 Tony Camuso 2016-06-24 13:30:51 UTC 
I am upgrading kmod to v22 with additional patches. 

Stay tuned ...
Comment 3 Chunyu Hu 2016-06-27 06:42:55 UTC 
Set ack+, sorry for the latency, as the default tester changed several times.
Comment 4 Tony Camuso 2016-06-28 14:09:51 UTC 
Too late in the game to upgrade to V22, so I backported some upstream patches. 

Please try the kmod rpms at this link:
http://people.redhat.com/tcamuso/kmod/ppc64le/

Please tell me if this fixes your problem.
Comment 5 Thomas Huth 2016-06-28 15:35:33 UTC 
Yes, that fixes my problem, there are no more annoying "unknown symbol .TOC." messages during "make modules_install" with these RPMs, thanks!
