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.

Pawel, Gerd,
Is the fix required to resolve this issue already upstream?
Thanks

No.  Possible solutions have been discussed (see linked mails in the original description of this bug), nothing merged so far, Pawel is busy creating a patch.

We discussed status of this bug this Tuesday. Following were latest updates on this.

- Pawel continues to work on this.
- This needs changes in qemu as well. Gerd has provided a patch to Pawel for qemu so that he can test firmware changes.
- Pawel and Gerd to discuss if changing data structure size is going to break something else in the system. Gerd is on sick leave, so I guess this part can make progress once Gerd is back. 

Pawel, do you have changes ready and tested so that Gerd (and others) can review it?
Comment 24 Paweł Poławski 2022-10-31 03:27:59 UTC 
Hi All, sorry I make you waiting.

I do not have code ready for this, just some raw draft. Will discuss this with Gerd
on Wednesday if possible (Tuesday is public holiday in Poland).
For last 2 weeks both me and Gerd were on PTO which delayed our sync also.
Comment 37 Vivek Goyal 2022-12-06 12:59:17 UTC 
There is no merged code for this upstream yet. So resetting it back to "ASSIGNED" state.
Comment 38 Vivek Goyal 2022-12-06 14:33:25 UTC 
Miroslav, is it some script which sets the status automatically from Assigned to POST. What we have currently there is just some Draft and its not about to be merged.

Yes, it's done by our gitlab checker. However, it is expect name in form "DRAFT: ...." to identify MR as draft. As the MR uses format "[draft] ..." it is not properly identified as draft MR. I updated MR to be in form we expect.
Comment 54 Xueqiang Wei 2023-01-17 08:19:05 UTC 
QE (pre verify): Set 'Verified:Tested,SanityOnly' as gating/tier1 test pass.
Comment 57 Gerd Hoffmann 2023-01-17 14:42:24 UTC 
For the record: The exact limit are: 1022 (old, without fix) and 8190 (new, with fix).
