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 3 Ben Crocker 2017-09-17 00:59:04 UTC 
The fix for this problem is embodied in the following Mesa commits:

commit 75cb6e36178b9474bbb59b76cbbcce2a67bf88d2
Author: Ray Strode <rstrode>
Date:   Wed Aug 23 16:32:42 2017 -0400

    gallivm: correct channel shift logic on big endian


commit 57c8ead0cd08e6aaf88a389f7ce528c4f0face65
Author: Ben Crocker <bcrocker>
Date:   Wed Aug 23 16:32:43 2017 -0400

    llvmpipe: lp_build_gather_elem_vec BE fix for 3x16 load

These commits do NOT appear to be in any of the Mesa
17.2.0 release candidates; we will need to do one of the following:

1) Apply these changes as a patch to 17.2;
2) Convince the Mesa folks to spin one more release candidate
   with this patch (seems unlikely, as Andres Gomez asserts that
   he has "completed the 17.2 cycle" with "17.2-rc6 as tentative
   final version to be promoted to 17.2.0 final."  The only
   encouraging word here is "tentative;"
3) Ship RHEL 7.5 with 17.2.1, which is not yet finalized
   (or even begun).
Comment 4 Ben Crocker 2017-09-18 14:43:56 UTC 
Crossed in the mail, apparently.
According to Emil Velikov, Mesa 17.2.1 is now available(!).
Comment 5 Ben Crocker 2018-01-31 22:23:57 UTC 
The version of Mesa supplied with RHEL 7.5 is actually 17.2.2 or greater;
since the fixes for this problem were in Mesa 17.2.1, this BZ should 
be closed.
