Error in linux upgrading from kernel 2.4.18 to 2.6.7
 

Hi,

I am currently working in linux kernel (2.4.18smp) ..i tried upgrading to 2.6.7.
Summary of what i have done.
1. Downloaded the source tar for kernel 2.6.7
2. Compiled the src files and installed.
3. Build the kernel and the modules.
All the above said did not list any errors, but while booting i get
the following error message:

mount: error 19 mounting ext3
pivot-root: pivot_root(/sysroot, /sysroot/initrd) failed: 2
umount /initrd/proc failed: 2
Kernel panic: No init found. Try passing init= option to kernel

Please help,

Which distribution are you using? Are you using some initial ramdisks to bootstrap the system? If so, have you configured your initrd for new kernel?

did you upgrade the modutils package..........the 2.6x kernel
requires...module-init-tools package now..........

Thanks for your response, I am not using initial ramdisks and my grub.conf looks like this
title Test Kernel (2.6.7)
root (hd0,2)
kernel /boot/bzImage-2.6.7 ro root=LABEL=/

I have not upgrade the modutils, Could you explain me on doing this or refer a link.
Thanks in advance.

Hi,
Thanks for the replay, masand.
With the help of doc from
/http://www.kerneltrap.org/node/view/2465
I was able to compile and install the kernel 2.6. When i boot, i encounter following problems though it finally boots.

Initialing USB Controller (USB uhci) : Fatal : Modul usb_uhci not found [Failed]

Initialing USB Keyboard : Fatal : Modul Keybdev not found [Failed]

Initialing Mouse : Fatal : Modul Mousedev not found [Failde]

applying iptables firewall rules bal bla bla bla
try IP tables-restore-h or iptables--restore bala bla bla : [Failed]

hi there
here is a extract from a document

USB
The names for the USB modules are different. This affects /etc/modprobe.conf (look for ``usb-controller'') and, once again, /etc/rc.sysinit. I had to rename all instances of ``keybdev'' into ``usbkbd'' and ``mousedev'' into ``usbmouse''. In addition, I replaced all instances of ``/proc/bus/usb'' with ``/sys/bus/usb''. (Also do this last part in /etc/init.d/halt.)
Look for ``needusbstorage'' in /etc/rc.sysinit. I changed that section into:
needusbstorage=
if [ $usb = "1" ]; then
needusbstorage=`LC_ALL=C grep -e "^I.*Cls=08" /sys/bus/usb/devices 2>/dev/null`
action $"Initializing USB HID interface: " modprobe hid 2> /dev/null
action $"Initializing USB keyboard: " modprobe usbkbd 2> /dev/null
action $"Initializing USB mouse: " modprobe usbmouse 2> /dev/null
fi
