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.

As one can see strings contain not expected values (the 1st 3 strings).

table 4 becomes correct:

i.e. with default 2.x SMBIOS tables strings in table 4 are misplaced or corrupted somewhere.
Likely by:
    t->core_count2 = t->core_enabled2 = cpu_to_le16(ms->smp.cores);              
...      
    t->thread_count2 = cpu_to_le16(ms->smp.threads);                             
...
unconditionally 'patching' earlier copied strings.
Comment 18 Julia Suvorova 2023-02-22 21:03:53 UTC 
Fix posted upstream:
    [PATCH] hw/smbios: fix field corruption in type 4 table
Comment 19 John Ferlan 2023-02-28 19:06:22 UTC 
Julia - I see you have an ACK on the v2 (https://lists.nongnu.org/archive/html/qemu-devel/2023-02/msg06751.html).

Can you please request the maintainer to do a pull request for the patch so that we can get it backported and tested downstream?  The ITM of 28 means we need this merged, tested, & validated downstream in by 13-Mar. We can always push that out a bit, but the sooner the better obviously since this is a blocker for the release.

Thanks!
Comment 24 dehanmeng 2023-03-08 07:26:38 UTC 
Hi all,

Just tried the fixed version of qemu-kvm, and the issue has gone and this case could be passed. 
thanks all for your effort and time.

Thanks

Hi Xueqiang,

Would you please help run an acceptance test against edk2 and seabios to verify this bz? Thanks.
