Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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.
---Problem Description---
On IBM Power 7 platforms with new P7 PCI Host Bridge, Emulex PCIe adapters require a
fundamental reset, rather than the default hot-reset to recover from ioa pci bus errors.
Latest version this has been seen on was RHEL 6.1 SS3.
---Additional Hardware Info---

---uname output---
Linux isquad1.austin.ibm.com 2.6.32-130.el6.ppc64 #1 SMP Tue Apr 5 19:52:26 EDT 2011
ppc64 ppc64
---Steps to Reproduce---
Use powerpc errinjct tool to inject PCI IOA bus error on Emulex PCIe adapter.
Observe adapter fails to recover, due to time out of mailbox 0x88, CONFIG_PORT command.
lpfc 0002:01:00.0: 0:0442 Adapter failed to init, mbxCmd x88 CONFIG_PORT, mbxStatus x0
Data: x0
lpfc 0002:01:00.0: 0:0442 Adapter failed to init, mbxCmd x88 CONFIG_PORT, mbxStatus x0
Data: x0
Patch has been submitted to Emulex for review and submission to Red Hat.
Patch has been tested on various P7 and P6 platforms with both PCIe and PCI-X adapters.
Testing confirmed there were no regressions and that patch allows recovery of injected EEH
errors in all cases tested.
Patch affects only Power PC platforms and does not affect AER recovery paths on Intel
architecture platforms.
Without this patch, customers using newer P7 platforms could be exposed to system crash or
loss of access to data should an unexpected pci bus error be detected. With this patch, such
pci bus errors would be recovered via Power PC Enhanced Error recovery.

Since RHEL 6.1 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.
Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.

Hello, I am assuming this message is some boiler plate message that was blanket attached to bugzillas and the the patch I submitted and tested has not and will not be removed from future RHEL6.2 kernels?
I talked to Richard and this patch came in under feature that updated the driver for RHEL 6.2, and he has confirmed that patch is in the beta build. so closing this bz as we no longer need it.
