Hi all,

I have installed slackware12.1 on vmware with kernel developement packages. I need to rebuilding the kernel for vmware drivers. Please help me for kernel rebuilding steps.

Thanks in advance

Hi all,,

I have installed slackware 12.1 on vmware. I have followed procedure to rebuilding the kernel, please help me

No filesystem could mount, tried:
kernel panic - not syncing: VFS: unable to mount root fs on unknown-block(8,2)

here is my configurations,

make mrproper
make menuconfig
make -j3 bzImage
make -j3 modules
make modules_install
cp System.map /boot/System.mapnew
cp .config /boot/confignew
cp /usr/src/linux/arch/i386/boot/bzImage /boot/vmlinuznew
mv /boot/vmlinuz /boot/vmlinuz-old


/etc/lilo.conf

lba32
compact
vga=normal

image = /boot/vmlinuznew
root = /dev/sda2
label = linux_2618
read-only

image = /boot/vmlinuz-old
root = /dev/sda2
label = linux_2433
read-only

/sbin/lilo -v

cd /boot
rm System.map
rm config
rm vmlinuz

Please help me

Thanks in advance

Wish configuration of the kernel you use, is it the huge one or the generic! it seems that the filesystem needed to boot is not built inside the kernel, so like that you have to do the initrd, depending on your fs, use this
mkinitrd -c -k (kernel version) -m (fs) .
example
mkinitrd -c -k 2.6.25.4-smp -m reiserfs

this will produce a image (initrd,gz) for you in /boot from the directory initrd-tree, in lilo
initrd = /boot/initrd.gz
lilo -v

you can also make some modification in /boot/initrd-tree and then you need only to do mkinitrd to compress the new image.

Please let me know if that was enough for you to solve your problem.
Regards.

Thanks for your response.

I have installed below kernels,

kernel-source-2.6.25.4
kernel-headers-2.6.24.5-x86-2
kernel-huge-2.6.24.5
kernel-modules-2.6.24.5
kernel-modules-smp-2.6.24.5

can you explain me difference between these kernels?

i have followed your procedures, but still same problem. can you tell me what modification we need to do in /initrd-tree?

Thanks
Geetha

kernel-source-2.6.25.4 1
kernel-headers-2.6.24.5-x86-2 2
kernel-huge-2.6.24.5 3
kernel-modules-2.6.24.5 4
kernel-modules-smp-2.6.24.5 5

1-is the kernel source for version 2.6.25.4
2-is the kernel headers files ( in other distro they called kerenl-devel)
3-kernel huge is compiled with almost all the features built inside the kernel
4-is the kernel drivers and modules.
5-is the kernel drivers and modules compiled with smp support ( symmetric multi processors) the kernel has to be compiled with smp otherwise will refuse to load these modules.


if you use Slack kernel huge so you don't care about the initrd, since the kernel will load any module if necessary, but you have to have the required modules installed with the same kernel version. for instance use kernel-huge-2.6.24.5 kernel-modules-2.6.24.5, usually you don't need to make modification in the initrd-tree, unless you want to add for example a boot splash screen a resume image or so on.

thanks for your response.

I have done below configurations after rebooting getting L 99 99 99 99 screen

mkinitrd -c -k 2.6.25.4 -m ext3

image = /boot/vmlinuz-custom-2.625.4
root = /dev/sda2
initrd = /boot/initrd.gz
label = newkernel

Please help me

That should work, i believe you forgot to run lilo -v before rebooting!
