build kernel failed

bhomass · 11-15-2005, 06:13 PM

I followed instructions on http://newbiedoc.sourceforge.net/sys...ILD-KERNEL-PKG
as closely as I could.

I could not make a boot floppy, because when I typed
mkboot /boot/vmlinuz-xxx, it says vmlinuz-xxx can not be read.

then when I ran
fakeroot make-kpkg clean,
it ran into permission problem.
so I ran the make-kpkg commands as root.

the new kernel-image.xxxx.deb was built. when I reboot, it stops at

can not open root device "hda1"

could someone tell me how to save this build? I don't remember if hda1 was the / partition. how do I find out? is that supposed to be the root device? hda is the correct disk drive though.

What was your make-kpkg command to make kernel-image.deb?

make-kpkg --append-to-version=.051115 kernel-image

as root!

I think (correct me if I'm wrong) what is recommend is to create a special user (dummy), put it in a new group (src).

Code:

su
addgroup src
adduser --ingroup src dummy

cd /usr/src
chown -R dummy:src linux-2.6.12.3
chown dummy:src .
chmod -R g+s linux-2.6.12.3

su dummy
cd /usr/src
ln -s linux-2.6.12.3 linux
cd linux

fakeroot make-kpkg clean && fakeroot make-kpkg --append-to-version=.051115 kernel-image

you should have your new kernel in /usr/src

su
cd /usr/src
dpkg -i kernel-image-2.6.12.3.051115.deb

ok found why the permission error. fakeroot make-kpkg clean ran fine.

make-kpkg kernel-image ran thru fine too. no error.

but on reboot, the same error. the exact error message is

VFS: Cannot open root device "hda1" or unknow-block (0,0)

I think I found the answer on
http://kerneltrap.org/node/970

it appear to me that adding --initrd in make-kpkg fixed it.

now the newly built kernel boots.

wonderful!
