Hi All,

Am running RHEL 6.0 and recently installed the new kernel rpms by following the steps mentioned here : http://www.linuxtopia.org/online_boo...m-upgrade.html

I did install rather than update so now I have two different entries for each kernel in the boot loader.

Initramfs was created successfully as part of install and the entry in grub.conf has also come good.

But when I select the new kernel at the grub, I get an error which reads something like this:
Failed to execute Init.
No Init found.

Am able to successfully boot the old kernel.

I checked the entry in the grub.conf and its exactly as the old kernel entry except for the version number.

I searched for this error and found some suggestions like add 3 to the grub entry, add init=/sbin/init, create initramfs manually using dracut but none of these worked for me.

If it can't find /sbin/init I'm going to guess the non-working kernel has the wrong boot device in its definition.

My grub.conf file is as shown below:

Entries are same for both the kernel except the version number difference and also I removed the 'quiet' option from the failing kernel to see if I can get some more logs.

Can I ask why you went for the Manual upgrade instead of 'Use Yum to Install Kernels Whenever Possible' as advised in that chapter?

That's because I do not have Red Hat Network subscription. I got the rpms from another team in my organization that had the subscription.
