no. Unfortunately the produced kernel files are not able to boot. In Fact the size is bigger than the original ones. This is the error reported :

I don't know why. Inside the kernel files It seems that everything is ok. I have placed the wrong files in my google drive. Maybe you want to test them on your side ? Thanks for your very very useful support. I can tell for sure that the quality and your patience are the best that I found on the internet.

Well, I've taken another look at your images. I have to guess
precisely what they show, as I've never used engrampa. But there's
one thing about #3 that I don't like the look of: The window
labelled "Posizione:" shows "/usr/share/plymouth/themes/homeworld",
but I assume that it refers to what's inside the cpio archive called
"initrd.img-5.10.0-18-amd64" highlighted in the window above.

If that's a conventional initrd, then I would expect "Posizione:"
to show "usr/share/plymouth/themes/homeworld", because I don't recall
ever seeing an absolute filename in an initrd. This could lead to your
writing to or reading from unexpected places in your filesystem,
depending on whoami. (Running these commands as root might perhaps be
one reason why you're writing /home/ziomario/… … … almost throughout).

That could be a red herring, but unlike mc, which may have to prefix
a filename with "/" to show it /is/ a directory, engrampa doesn't
need that indication here, because it puts a "/" after homeworld,
which shows the same thing.

Anyway, contrast:

$ find /etc/resolv.conf /etc/networks -print | cpio -ov > /tmp/absolute.cpio
/etc/resolv.conf
/etc/networks
1 block
$ find /etc/resolv.conf /etc/networks -print | cpio -ov --no-absolute-filenames > /tmp/relative.cpio
cpio: Removing leading `/' from member names
/etc/resolv.conf
/etc/networks
1 block
$

which list as:

$ cpio -t < /tmp/absolute.cpio
/etc/resolv.conf
/etc/networks
1 block
$ cpio -t < /tmp/relative.cpio
etc/resolv.conf
etc/networks
1 block
$

You should be using files that look like relative.cpio.

Cheers,
David.
