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.

rhel-6 network install crash on ppc64

Description of problem:

While trying to do a netwrork install of rhel-6 with yaboot, the kernel panics when it tries to mount the root partition.

Version-Release number of selected component (if applicable): rhel-6 beta 1

How reproducible: always

Steps to Reproduce:
1. Setup a tftp server with yaboot and rhel-6 installation files (vmlinuz and ramdisk.image.gz) from the ppc/ppc64 directory on the DVD.
2. Boot the LPAR in network mode (SMS)

Actual results:

Yaboot loads the files, boots the kernel and then the kernel crashes.

Expected results:

The kernel doesn't crash and anaconda starts.

Additional info:

In the beginning I couldn't even get this far, a crash occured in OF. Then, I started to try some alternate values for the real-base parameter in OF. Finally, I got into this with real-base = 0x3000000...

This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux major release.  Product Management has requested further
review of this request by Red Hat Engineering, for potential inclusion in a Red
Hat Enterprise Linux Major release.  This request is not yet committed for

My tftp setup was wrong and I wasn't using the right yaboot... Now everything is okay.

Sorry for any inconvenience.
