Hi, Shachar.
stack has following structure:
argc

auxv
You can see auxv by running any dynamically linked executable as
LD_SHOW_AUXV=1 program
What you are looking for is AT_ENTRY
Code that initialized user_entry is in the

Here's a piece of trivia for you.

Actually, I can think of four or five reasons why it may fail, but I'll
cross those bridges when I get to them.
And if you change AT_ENTRY in the auxv you'll trick ld-linux to think

We encountered a grub weirdness and I can't find any reference to this issue

Hi,
The blue menu doesn't appear, only the prompt.
Everything is identical the only different between before and after is
that the tar.gz is based on stable kernel, while the installer was based on
a testing kernel.
But that shouldn't affect it, as I am basically replacing everything...

Can you boot anyways? Take the commands written in the menu.lst file
under the kernel version you want and type them at the prompt one at a
time, adding boot as the last command. It should start the right kernel.

Hi,
The problem is solved, the error still there if I do it from the rescue disk,
but it boots if I do it manually from the grub prompt.
Once it booted, I re-run grub-install and now it works without doing it from
the prompt :)
Thanks guy.
