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.

Any word on this one?

Here's a little more info from the failure I saw:

Kernel panic - not syncing: Attempted to kill init! 
Pid: 1, comm: init Not tainted 2.6.32-306.el6.x86_64 #1

This was also seen on a different RHEL6.4 install attempt in sys.log:

This happens, when dracut (process 1) stops. In this case because of:
dracut Warning: dracut: FATAL: Initial SELinux policy load failed. Machine in enforcing mode. To disable selinux, add selinux=0 to the kernel command line. 
dracut Warning: dracut: Refusing to continue

Well, seems like selinux is broken! Dracut cannot do anything about it.
Comment 4 Daniel Walsh 2012-09-26 21:12:03 UTC 
Is selinux-policy package installed?
Comment 5 Scott Poore 2012-10-04 19:16:59 UTC 
I'm guessing it was included in the image used for that phase of the kickstart boot/build.  I guess I don't know that for sure though.

This may be resolved now though.  I was able to successfully build a RHEL6.4 test with the latest build and it seems fine.
Comment 6 EricLee 2013-05-29 06:35:19 UTC 
Hi All,

I got the same error when I install VMs, the strange thing is that: I use the same profile to install two guests which with different disk format(one is qcow2, the other one is raw), only raw format disk will get the error after installed and can not boot up normally. Please see the attachment.

Can somebody tell me what's the problem?

Thanks,
Ericlee

Comment 8 Salim Talamas 2014-05-14 16:43:07 UTC 
We also had experienced the same issue as noted above on rhel 6.4.  To resolve the issue we did the following:

Problem: after disabling selinux, we encountered the following kernel panic -not syncing: Attempting to kill init!

Solution: 
Step1 - boot into rescue mode via rhel ISO image
Step2: navigate to the filesystem: /mnt/sysimage/etc/selinux/config 
Step3 - modify selinux=0 then reboot
Step4 - boot normally to rhel OS
Step5 - from CLI getenforce will display "Permissive"
Step6 - navigate to /etc/selinux/config and modify selinux=disabled
Step7 - reboot normally to rhel OS. Kernel panic should not occur
Step 8 - confirm getenforce displays "Disabled"
