Hi All,
I am trying to build and compile a new kernel. Currently, I have
linux-2.6.25.11-97.fc9.i686 installed on my machine, which I use to
build and compile the new kernel for linux-2.6.19.2. I follow the
standard procedure for building and compiling the kernel, but still I am
unable to boot my machine from the new kernel. I get the following
errors when I try to boot the machine from the new kernel:-
Uncompressing Linux... OK, booting the kernel

There are 3 possibilities.
#1: is you don't have the device driver needed for old kernel in the initrd.
#2: That device driver in 2.6.19 does not work at all for your hardware or does
not exist for your hardware in 2.6.19.
#3: The old kernel won't work for your hardware at all because of other issues.
There are *NO* easy solutions if the problem is #2 or #3, and if your hardware
has a newer chipset than existed when 2.6.19 was released then #2 or #3 are very
possible.
If it is #1 you need to see what the original kernel loads to drive the disk
subsystem and see if that is enabled, and installed in the initrd in 2.6.19, and
any modules that it needs are there with it.
You might try some older recovery CD's, if you find one that works and it is a
kernel from around 2.6.19 then you would be able to find the module names used
in 2.6.19. I believe a number of the disk modules names have been changed
around since 2.6.19 so very likely you don't have the proper module being
included in the initrd.
