What is the path to the login program? What is it labeled? The problem
is login is running with the wrong context.
It should be labeled login_exec_t
grep :login_exec_t /etc/selinux/targeted/contexts/files/file_contexts
/bin/login -- system_u:object_r:login_exec_t:s0
/usr/bin/login -- system_u:object_r:login_exec_t:s0
/usr/kerberos/sbin/login\.krb5 -- system_u:object_r:login_exec_t:s0
init_t is supposed to transition to local_login_t when executing the
login program.

Hi Daniel,
Thanks for quick reply. Please find first time boot log with lableling
and reboot.
Also find second time boot log when I created /.autorelablel.
Somehow I could not able to login as root.
Your help is really appriciated.
Thanks,
Srinivas.

Looks like you have a labeling issue.
touch /.autorelabel; reboot
Should fix the issues.
