kernel upgrade problem

[riteshudhani]

Hi,

I am using RHEL 5.0 with kernel version 2.6.18-8.e15. Since my wireless hardware "Intel wireless wifi link 5100" is not detected in this, I am trying for upgradation of kernel to 2.6.26.1 which supports this hardware, as I read on Intel's website.

I downloaded full source(as opposed to the patch) in /usr/src and extracted it in /usr/src/kernels(got /usr/src/kernels/linux_2.6.26.1 folder). There I did the following:
1) make menuconfig(I modularied a wireless section)
2) make(to build the kernel)
3) make modules(to build the modules)
4) make modules_install(to install the modules)
5) make install(to install the new kernel)
6) After that I edited grub.config as:
title Red Hat Linux (2.6.26.1)
root(hd0,2)
kernel /vmlinux-2.6.26.1 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.26.1.img
All went well and I didnt get any errors or any problem in following the above steps.

Now when I restarted my laptop and tried to boot using 2.6.26.1 kernel, I am not able to do so as I get the following on screen:

Unable to find volumegroup
(and messages like unable to find /dev/root
unable to find /proc etc)
Kernel panic: Not syncing-Attempted to kill init!

I tried to look for a solution in this forum, people have asked this before but I didnt get a fix yet. Kindly help me with this problem as I am stuck with this for 2 days now. Please let me know what should be done as to rectify any problem, if any, which exits.

i have been doing the same thing.....but in grub.conf i have given a wrong scource to the kerenl image......now i am not able to boot......can u tell me way how can i boot my
old image.

when you get the grub boot loader, edit it and make it the same as the old one(for instance u might only have to change the kernel version keeping the rest as same-this is valid only if the vmlinuz and initrd files of the old kernel is still there in /boot and u have not replaced it with the new one)
