Install 11gR2 on RedHat 6 or OEL 6

Question

Hi All,
I am installing 11gR2 on our Linux RH 6  server.
I got this pre-req setup for the install guide in ORACLE-BASE website (one of my idol site).
But when I restarted the server, I got error kernel panic , and can not boot the server
What parameter here caused it to panic? It did not mention specifically. 
Please Helpppp...Thanks.
Hosts File
The "/etc/hosts" file must contain a fully qualified name for the server.
<IP-address>  <fully-qualified-machine-name>  <machine-name>
For example.
127.0.0.1       localhost.localdomain  localhost
192.168.0.181   ol6-112.localdomain    ol6-112  
Oracle recommend the following minimum parameter settings.
fs.suid_dumpable = 1
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586
Add or amend the following lines in the "/etc/sysctl.conf" file.
fs.suid_dumpable = 1
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
#semaphores: semmsl, semmns, semopm, semmni
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default=4194304
net.core.rmem_max=4194304
net.core.wmem_default=262144
net.core.wmem_max=1048586  
Add the following lines to the "/etc/security/limits.conf" file.
oracle              soft    nproc   2047
oracle              hard    nproc   16384
oracle              soft    nofile  4096
oracle              hard    nofile  65536
oracle              soft    stack   10240
Amend the "/etc/security/limits.d/90-nproc.conf" file as described below. See MOS Note [ID 1487773.1]
# Change this
*          soft    nproc    1024 
# To this
* - nproc 16384
Set secure Linux to permissive by editing the "/etc/selinux/config" file, making sure the SELINUX flag is set as follows.
SELINUX=permissive
Once the change is complete, restart the server.
