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.

Since BZ961178 ("[aarch64] [kernel] Add support for pvpanic-pci"), the pvpanic-pci  driver is compiled. Unfortunately it isn't loaded automatically when the guest is exposed with the pvpanic-pci device and for the use case to work, a manual modprobe is required. This BZ to add the auto-load modality using MODULE_DEVICE_TABLE macro in the driver (tentative).

"[PATCH v2] misc/pvpanic-pci: Allow automatic loading" is under discussion on the ML.

Hello Eric,

Do we plan to fix this bug in 9.0 Beta? 
If the fix is planned, we need to set up the DTM.
After this, I will set up ITM.

thanks

ZhenYu

Hi Zhenyu, a fix was sent upstream and is waiting for review. I cannot guess when this will land upstream as it missed v5.14, so I cannot set any DTM atm. Thanks. Eric

The fix has landed upstream in 5.15
