Hi,

I have RHEL 4 AS installed on my desktop PC (INTEL Pentium D
processor). My RHEL distribution has 2.6.9-34Smp kernel.

I tried to upgrade my kernel to 2.6.20, for this I downloaded 2.6.20
kernel, compile it and install it (using make, make modules_install
and make install).
Few warning comes on compilation and installation.

But on rebooting and running my new kernel hangs.
I have tried to debug the issue and on adding prints to init/main.c
file, I found that kernel is hanging somewhere inside the 'init'
program present in the ramdisk.

Here is some additional information, on running kernel without "quite"
param last few lines that apears on console are:
"
Time: tsc clock source has been installed
input:ImPS/2 Logitech wheel Mouse as /class/input/input0
input:AT Translated Set 2 keyboard as /class/input/input1
"
After that there is no prints, but my keyboard is still active (LED on
it glows up on pressing Num Lock key)

Grub.conf entry for this kernel is:
title Red Hat Enterprise Linux AS (2.6.20)
root (hd0,8)
kernel /boot/vmlinuz-2.6.20 ro root=LABEL=/ rhgb
initrd /boot/initrd-2.6.20.img

Do I missing something? Please provide a pointer to debug further.

Thanks,
nandac

Did you configure the kernel before compiling it? The easiest way is to copy over the .config file from your old kernel to your new kernel's source directory and run make oldconfig before running make.
