I have just upgraded my RH7.1 kernel from 2.4.2-2 to 2.4.14.
Everything seemed to go well, the system rebooted ok.
I made a symbolic link to my new kernel as well as the System.map.
Here is what is has me stumped.
When I boot the machine, even though I created a new kernel (vmlinuz)
as well as a new support file (System.map) I still get a message
stating that I am still running Linux 2.4.2-2.
If i go to a menu and do a uname -sr it still tells me that I am
working with Linux 2.4.2-2 Where did I go wrong. I made sure that I
changed my lilo.conf file so that image is vmlinuz, which is soft
linked to vmlinuz-2.4.14.

I did notice that whn I looked in the /etc area, the following links
are still pointing to version 2.4.2-2 stuff

kernel.h -> kernel-2.4.2
module-> kernel-2.4.2-2

As I was typing this I ran lilo from /sbin/lilo, now the machine gets
to Loading Linux ..................
then it does nothing but reboot!
I tried using the boot disk and after it loads half way I get a
message stating Kernel Panic: No init found

any ideas on where I may have went wrong?

Thanks,

If it would help, I can type the steps that I used?

Did you build modules? Why don't you post how you built the kernel
2.4.14?

Uhm, did you run /sbin/lilo on your new lilo.conf? If you don't do this,
changes to lilo.conf have no effect. Quote from the lilo docs: "You can't
run lilo often enough."

I once had the same problem after recompiling a kernel. It turned out I'd
configured it to use the wrong kind of CPU. Are you sure you configured
your new kernel correctly, e.g., for your processor type etc? Either you
made a mistake there, or you have a corrupted kernel (corrupted vmlinuz
file?)

This sounds like an unrelated problem. init is the very first program
that the kernel starts. So, this usually happens when the kernel can't
find the correct root file system (usually, init is on it). If you're
using an initial ramdisk, then something may be wrong with that.
Or you could have forgotten to build support for your root filesystem
into the kernel (NOT as a module). Or maybe the bootdisk you use is old
and you've moved your root filesystem to a new partition.

Hope some of this helps.

As an afterthought, you do know that you need to use the right gcc
version (probably egcs 2.91.66) to compile a kernel, right? I forgot this
the other day and had horrible results which I couldn't explain, until
someone reminded me to use the correct compiler.

On RedHat 7.0, they included this stupid broken gcc 2.96 implementation.
I'm not sure if that's still the case in RH7.1. If it is, edit the
makefile to use kgcc instead of gcc. Or replace the compiler.

Oh, god... not another digressing thread about that icky, horrible,
stoopy-poopy gcc 2.96 again...

gcc 2.96 compiles kernels just fine... stop spreading inaccuracies and fud.
