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 5 RHEL Program Management 2010-07-15 14:08:10 UTC 
This issue has been proposed when we are only considering blocker
issues in the current Red Hat Enterprise Linux release. It has
been denied for the current Red Hat Enterprise Linux release.

** If you would still like this issue considered for the current
release, ask your support representative to file as a blocker on
your behalf. Otherwise ask that it be considered for the next
Red Hat Enterprise Linux release. **
Comment 6 Larry Troan 2011-10-05 13:36:01 UTC 
Pushing to 6.3 for consideration.
Comment 7 Don Zickus 2011-12-13 17:26:07 UTC 
This has been most likely addressed in later RHEL-6 kernels.  Otherwise this would have been revealed in AMD's testing by now.  There were a bunch of patches to detect the northbridge properly that went in after the affected kernel.

I would re-test and then close as current release upon success. :-)

Cheers,
Don

I was able to use Beaker and query for recent RHEL6 jobs that were run on this hardware
Comment 9 Don Zickus 2011-12-13 18:20:41 UTC 
So the problems seems to have disappeared with the latest bits.  Great!  Closing then as CURRENTRELEASE.

Cheers,
Don
