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.

in kernel-2.6.32-71.4.1.el6
Comment 4 Gris Ge 2010-10-15 07:23:07 UTC 
Cannot reproduce this issue with "Emulex LPe12002-M8".
It's firmware version is :
1.11A5 (U3D1.11A5), sli-3

Kernel version: 2.6.32-71.el6.x86_64
Reboot 5 times, no lpfc kernel panic came out.

As Bug #634703 spot out:
>Emulex believes there is exposure to this issue in large SAN environment where
>the device discovery process could see delayed responses which result in iocbs
>being queued.

Do we need a large SAN environment to reproduce this issue?

Very likely you do.
Comment 6 Barry Donahue 2010-10-21 14:50:52 UTC 
I added 20 more SAN disks to the configuration and did a one hour reboot cycle for the system.
