RE: kernel panic

["Abu M. Muttalib" <abum@xxxxxxxxx>]

Hi,

 

Please look for the discrepancy between...

 

title Red Hat Linux (2.4.20SAHUTEST)
        root (hd0,0)
        kernel /vmlinuz-2.4.20SAHUTEST ro root=/dev/hda3
        initrd /initrd-2.4.20SAHUTEST.img
title Red Hat Linux (2.4.20-8)
        root (hd0,0)
        kernel /vmlinuz-2.4.20-8 ro root=LABEL=/
        initrd /initrd-2.4.20-8.img

The first option is incorrect where in you have specified root=/dev/hda3,

 

specify the same what you have specified for second option..

 

I guess you are trying to boot with option 1, where you are getting error at boot time.

 

CMIAW.

Subject: kernel panic

hi all,
  i have installed 2.4.20-8.i am trying to recompile the kernel by following these steps:
edit the makefile for extraverion as (SAHUTEST)( i am )
make oldconfig
  make dep
  make bzImage
  cp arch/i386/boot/bzImage /boot/SAHUTEST
make modules
make modules_install
make install
reboot

during booting i am getting an error as:
VFS :cannot open root device "LABEL=/" or 00:00
please append a correct "root=" boot option
kernel panic: VFS:unable to mount root fs on 00:00

please suggest me the solution as soon as possible!

the partition is as follows:
Filesystem          1K-blocks      Used Available Use% Mounted on
/dev/hda3            10080520    165600  9402852  2% /
/dev/hda1              505605    17957    461544  4% /boot
/dev/hda5              1004024    16428    936592  2% /home
/dev/hda2            10080520    32828  9535624  1% /opt
none                    126872        0    126872  0% /dev/shm
/dev/hda7            15780852  2430556  12548656  17% /usr

the grub.conf file is as :

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/hda3
#          initrd /initrd-version.img
#boot=/dev/hda
default=1
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title Red Hat Linux (2.4.20SAHUTEST)
        root (hd0,0)
        kernel /vmlinuz-2.4.20SAHUTEST ro root=/dev/hda3
        initrd /initrd-2.4.20SAHUTEST.img
title Red Hat Linux (2.4.20-8)
        root (hd0,0)
        kernel /vmlinuz-2.4.20-8 ro root=LABEL=/
        initrd /initrd-2.4.20-8.img
title test
        root (hd0,0)
        kernel /test ro root=LABEL=/
        initrd /initrd-2.4.20-8.img
