Where is your new "initrd-2.4.21.img" image ?
I did a

[root@postel ~]# /sbin/mkinitrd -v -f /boot/initrd-2.4.21.img 2.4.21

/sbin/nash -> /tmp/initrd.AR5054/bin/nash
/sbin/insmod.static -> /tmp/initrd.AR5054/bin/insmod
[root@postel ~]#
I guess its in /boot/

Did you build this while compiling the kernel ? I mean using the same
System.map file.
I did this while I was booted in the 2.6 kernel. This was outside the kernel compiliation direction and have tried it couple of reboots after the kernel compilation.


It seems that you created a new image at /boot/ location ? try without
initrd image.
How? Should I disable initrd in the .config?

Mostly various distributions have different method for
creating initrd image.

You can also refer to this thread(its a thread I posted with my alias) for the error message I am having.

as my painful experience with FC3, it MUST bootup with an initrd.

this panic message looks familiar with me, since you have an initrd made,
can you show me your grub config ? (or lilo )

Hi All,

I am running FC3 with a 2.6.10 kernel without any problems.

I am trying to install a 2.4.21 kernel for an application I am working
on. Initially I had problems compiling the 2.4 and after a lot of
effort, I changed the gcc to the right version (2.96.3) and was able to
compile the 2.4.21 kernel. I also had a problem with 'make
install_modules' that version reqired old depmod and I had to create a
symlink "ln -s /sbin/depmod /sbin/depmod.old". And finally it compiled
and installed.

But when I try to boot this new 2.4.21, I get a kernel panic message
saying:-

And now I am getting this message:

/***************************************************************/
kjournald starting. Commit interval 5 seconds
EXT3-fs: mounted files system with ordered data mode.
pivotroot: pivot_root(/Sysroot,/Sysroot/initrd) failed: 2
umount /initrd/proc failed: 2
freeing unused kernel memory: 276k freed
Kernel panic: No init found. Try passing init= option to kernel.
/***************************************************************/

Any pointers, folks?

I also I ran a

/sbin/mkinitrd -v -f /boot/initrd/2.4.21.img 2.4.21

without any use.

Thanks,
K
