problem compiling kernel
Hi to Everyone,
I need to re-compile my kernel so that it does not include sound support
inside. I am running Debian 3.1 (Sarge). My system is on RAID1. My /boot
partition is from /dev/sda1 (mirror on /dev/sdb1) installed on /dev/md0
(ext3), while my '/' partition is from /dev/sda2 and /dev/sdb2 installed
on /dev/md1 mounted on /dev/mapper/vg00-root (LVM2). It's been working
OK for several years.
The easiest way would be to try re-compiling from
/boot/config-2.6.20-16-386 using make oldconfig. But this repeatedly
fails. 'make' soon returns error messages saying that such and such
function have not been declared. Since the process works with more
recent kernels, I suppose that the Makefile that I have in
/usr/src/linux-2.6.20-16-386 is buggy, or else, maybe the version of
gcc/make that I get is no longer compatible with said Makefile : I must
admit that I have sometimes ran 'apt-get install' on various packages
with a /etc/apt/sources.list that contained lines referring to testing
directories.
So, upon my failures to recompile kernel 2.6.20-16-386, I tried
downloading 2.6.20-17-386, but I got the same results. However, with
2.6.26.2, it did compile without errors... but in the end the image
won't boot !
My compiling process does not generate initrd.img, so I did generate one
using 'mkinitrd', and I wrote its path in /boot/grub/menu.lst with the
kernel image.
Here is what I get on booting trials :
boot starts, as usual text displays very fast and you cannot read until
it stops. When this happen, I can read this :
"
md: raid0 personality registered for level 0
md: raid1 personality registered for level 1
device mapper................
.........................................
no filesystem could mount root. Tried: cramfs
kernel panic - not syncing: VFS unable to mount root fs on unknown
block(0,0)
"
So, I re-tried compiling after de-activating raid0 in the config,
leaving only raid1... to the same end result.
Could someone tell me what options I should select in the config so as
to obtain a new kernel that will boot my RAID architecture ?
I know that there are other ways to compile Debian kernels, using
'make-kpkg', but this does not work here, likely because this tool
version is too old or too new for my system : it keeps saying that
parameters are missing, while the howtos that I saw did not mention any
such parameters for make-kpkg.
By the way, I noticed that the initrd.img that I obtain using mkinitrd
are about 5 times bigger than that which is used to boot my usual
kernel. I am not sure that I am using mkinitrd correctly.
mkinitrd -o initrd.img-2.6.26.2 2.6.26 done from /boot issues an error
messages saying that this image will not take raid into account, and
that therefore it won't boot, unless the main image contains what is
missing here. In any case, it doesn't boot. The same command issued in
/usr/src/linux-2.6.26.2 does not send any error message, but in the end
the image doesn't boot either.
Thanks in advance for your help
