Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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.

Comment 1 Vladimir Benes 2022-01-27 14:54:38 UTC
not sure if the third bug is related but there is one more
https://jenkins-networkmanager.apps.ocp.ci.centos.org/job/NetworkManager-main-c9s/75/artifact/FAIL-report_NetworkManager-ci-M0_Test0318_dracut_legacy_iSCSI_ibft_table.html

We can file a new bug for this one if needed (but we somehow planned to turn off legacy dracut tests completely). What do you think?

It's not clear what's happening there, as NM completes the configuration and one minute later there are I/O errors. Anyway, it looks like a different issue. If it happens again, please file a separate bz.

Comment 3 Beniamino Galvani 2022-02-02 09:06:07 UTC
BTW, I was not able to reproduce the failure even after running the test in loop for hundreds of times; it seems the issue happens only when, for some reasons, udev annonces the interface late.

I could reproduce the failure by rebuilding the initrd image with an additional service that sends SIGSTOP and SIGCONT to udev so that messages get delayed. It's a hack, but I'm attaching in case it's useful for verification. Maybe the service could have a ConditionKernelCommandLine= so that we can activate it when needed, and we could add a test for it.
