Problem in installing new kernel

[Pranav Tendulkar]

hello,
i am a new user to Red Hat Linux Enterprise Edition 4.1
I am trying to install a new kernel 2.6.15.6 on my Linux.

I have compiled the kernel and copied bzImage to /boot partition.
Also I have modified the grub.conf file
it is listed as

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,2)
# kernel /vmlinuz-version ro root=/dev/sda6
# initrd /initrd-version.img
#boot=/dev/sda
default=2
timeout=5
splashimage=(hd0,2)/grub/splash.xpm.gz
hiddenmenu
title Red Hat Enterprise Linux 2.6.15.6
root (hd0,2)
kernel /vmlinuz-2.6.15.6.img ro root=LABEL=/ rhgb quiet
initrd /initrd-2.6.15.6.img
title Red Hat Enterprise Linux AS (2.6.9-5.ELsmp)
root (hd0,2)
kernel /vmlinuz-2.6.9-5.ELsmp ro root=LABEL=/ rhgb quiet

initrd /initrd-2.6.9-5.EL.img

this is listing of /dev/sda

[root@localhost grub]# fdisk /dev/sda

Command (m for help): p

I managed to find out my hardware.
I have SCSI hard disk installed on my PC.

so I have enabled the SCSI support in the configuration.

But now this has given rise to new error solving the previous ones...

the last message that appears on the screen when i boot is

Enforcing mode requested but no policy loaded.Halting Now
Kernel Panic : No syncing : Attempted to kill init !!!

Hi

Do you want to compile a new kernel or just install a newer one...if you just want a newer kernel, downlaod the latest kernel in rpm and then do rpm -ivh kernel-newxxxx.rpm

Cheers

I have already downloaded the latest kernel which was in zipped format...
i have compiled that kernel and tried all the stuff mentioned above... :(

You did not described the steps used to build the kernel. As described before, installing a new kernel from the rpm file is the easyest way. Maybe you omitted required modules and your initial ram disk is not working.

[Vitaly Karasik_1]

You should copy initrd image to /boot directory.
And of course, using kernels provided by Red Hat is the recommended way.

[Pranav Tendulkar]

I have already created a new initrd into the boot directory with the help of a command called mkinitrd.

Hey guys,

thanx a lot for all your support.
I have cracked the problem.
It was due to SELinux.
I disabled SELinux in /etc/selinux/config file.
And now my installation worked perfectly fine :)

Thanks a lot....
