Hi Everyone,
I have installed RHES 2.1 installed on my machine, which comes by default with kernel-2.4.9-e.24. It works well. I recently upgraded to kernel 2.4.18-27.7.x using kernel RPM as follows:
rpm -ivh kernel-2.4.18-27.7.x.i686.rpm /sbin/mkinitrd -f -v /boot/initrd-2.4.18-27.7.x
I am using grub as the bootloader and it has following configuration for booting into new kernel:
title Red Hat Linux (2.4.18-27.7.x) root (hd0,0) kernel /vmlinuz-2.4.18-27.7.x ro root=/dev/hda3 initrd /initrd-2.4.18-27.7.x.img
When i boot into new kernel i get following error:
pivotroot: pivot_root(/sysroot, /sysroot/initrd) failed: 2 Freeing unused kernel memory: 160k free Kernel panic: No init found. Try passing init= option to kernel.
Thing to note. I can still boot to older kernel and works well.
Any one any ideas what could be the problem in here? Any help on the matter will be appreciated.
Thanks and Regards, Nikunj

doesn't it require one more parameter? seems kernel version param is missing.
title Red Hat Linux (2.4.18-27.7.x) root (hd0,0) kernel /vmlinuz-2.4.18-27.7.x ro root=/dev/hda3 initrd /initrd-2.4.18-27.7.x.img
try bootin in the new kernel after removing initrd entry from grub.conf for the new kernel.

Hi Guys,
Finally got the problem solved:
Here is a brief problem description and solution in my case:
Problem Description:
I have installed RHES 2.1 installed on my machine, which comes by default with kernel-2.4.9-e.24. It works well. I recently upgraded to kernel 2.4.18-27.7.x using kernel RPM as follows:
rpm -ivh kernel-2.4.18-27.7.x.i686.rpm
/sbin/mkinitrd -f -v /boot/initrd-2.4.18-27.7.x 2.4.18-27.7.x
I am using grub as the bootloader and it has following configuration for booting into new kernel:
title Red Hat Linux (2.4.18-27.7.x) root (hd0,0) kernel /vmlinuz-2.4.18-27.7.x ro root=/dev/hda3 initrd /initrd-2.4.18-27.7.x.img
When i boot into new kernel i get following error: (I have added comments as I understand after some research in Italics after the errors)
mounting root filesystem kmod: failed to exec /sbin/modprobe -s -k block-major-3, errno = 2 >> run modprobe on block-major-3 i.e. IDE Drive and errno=2 signifies cannot find file. mount: error 6, errno = 2 >> Cannot find IDE Disk so cannot mount it. And all other error follows. pivotroot: pivot_root(/sysroot, /sysroot/initrd) failed: 2 Freeing unused kernel memory: 160k free Kernel panic: No init found. Try passing init= option to kernel.
Solution:
Problem was my BIOS (version BF86510A.86A.0038.P08) allowed to configure ATA/IDE Drives on enhanced mode which has all PATA and SATA Resources enabled (comes by default), but new kernel identifies IDE Drives only in LEGACY Mode (Primary /Secondary). I changed the BIOS Settings for IDE Drives from Advanced to LEGACYand it works fine.
Let me know if you have any doubts/clarifications.
