Kernel Panic

Jahanzeb — Sat, 09 Aug 2003 15:09:23 GMT

Hi ........
this is Jahan,
I have created a bzImage for Redhat Linux 9 with kernel version 2.4.20-8. After making the necessary changes in the grub.conf file, when I reboot my system with the new kernel, then the system gives me the following messages.

mount: error 19 mounting ext3
pivotroot: pivot_root (/sysroot, /sysroot/initrd) failed: 2
umount /initrd/proc failed : 2
freeing unused kernel memory: 156 k freed.
kernel panic : no init found. try passing init = option to kernel

Can anyone help me that how I can rectify this problem.

Thanks.

Hi Jahan,

There are good chances that your system doesn't find its partitions. Could you post :

- your grub.conf file ;
- your /boot content.

Tks

did you create/define in grub.conf initrd file for your kernel?

Hello Dear

Here is the grub.conf

did you include support for ext3 filesystem in your kernel?

Jahanzeb — Sun, 10 Aug 2003 13:10:57 GMT

Hi dear Henry...

Thanks for your instant response,
and I am afraid that I don't know how to add the support for ext3 filesystem in Linux kernel. Would you be so kind to let me know that how to do this.

Thanks.

Jahan

Unless you specifically went out of your way to exclude it ext3 filesystem support is in your kernel.

It would appear that my may have a disk/hardware problem. Is the behavior consistent?

State your version of Linux. Looks like 7.3.

Jahan,

Look under "file systems" for ext3 in your kernel config and make sure it is compiled into the kernel and NOT selected as a module. (Modules for the root file system can be made to work at boot, but that is another story:))

AFAIK, in RH Linux kernel compiled with ext3 as module. Just because it RHL uses initrd by default.
