hi,
i have to recompile a kernel (2.6.25.9) to get some hardware working,
for example network cards and 3ware SCSI SATA controller from the
installer (debian-testing-amd64-netinst.iso). But I'm unable to create a
valid kernel and/or initrd.
i did something like:
# mount loop .iso
# copy the contents into a directory
# compile kernel and copy them to cd/install.amd/vmlinuz
# unpack initrd.gz
# copy the modules to lib/modules
# recompress with cpio and gzip
(cd ramdisk/ ; find . -depth -print | cpio -oc > ../newinitrd ; cd .. ;
gzip newinitrd)
# copy the new initrd.gz to cd/install.amd/initrd.gz
# create mkisofs
# starting ...
But, however. I get
a) tried reiserfs,ext3,ext2,cramfs .... "Kernel panic - Unable to mount
...."
b) or if i do mkcramfs ramdisk/ new.cramfs and copy them to
cd/install.amd/initrd.gz, i get "Unable to mount root fs on
unknown-block(253,0)"
and he lists some partitions from ram0 till ram15. He said, i tried to
boot from <NULL> as root=
so, what i have to do. Most pages and Howtos are old. I want to change
only the kernel with his modules, nothing more.

Where to start... well, I don't know your level of sophistication with
the kernel, but did you compile the kernel the "Debian way" or the
standard way? Did you use a Debian kernel (looks like not) or a vanilla
kernel? Did you use make oldconfig? If you did it the Debian way, did
you,
$ cp /boot/config<your old version>
$ make gconfig <---- if using gnome, otherwise some variant
$ make-kpkhg clean
$ make-kpkg --initrd kernel_image modules_image
$ cd ..
$ dpkg -i linux-image*.deb
If you used a non-Debian kernel, did you,
$ make mrproper
$ make oldconfig
. . .
or maybe
$ make mrproper
$ cp /boot/config<your old version>
as a starting point? And then, possibly,
$ make gconfig
$ make
$ make modules
$ make modules_install
$ depmod -a
$ update-initramfs -c -k <yourversion>
$ make install
or some variation on the above? (Some of the steps above may be
redundant.)
Do you have all the build tools installed? For Debian way, you need
packages build-essential, init-ramfs-tools, kernel-package,
module-assistant, devscripts, and of course the kernel package, and the
dependencies. You might need git-core, or fakeroot, depending on you
setup. ncurses is needed for some of the config tools, and maybe other
things (you also need ncurses-dev).
A typo up there, should be make-kpkg clean.
Also, this all assumes that you are working from the standard directory
/usr/src/linux-source-<yourversion>
These are just some hints or guidelines, you should read the kernel docs:
/usr/src/linux-source-<yourversion>/Documentation
And other stuff. Plenty of stuff on the web, with some diligence
searching. (In English, the kernel does not use the masculine pronoun.
It is usually referred to as an 'it', not a 'he'.)
