Kernel panic while upgrading from 2.4.20-6 to 2.4.22

Kernel panic while upgrading from 2.4.20-6 to 2.4.22

[Elwin Eliazer]

Hi,

I am getting kernel panic, when i try to upgrade my
kernel from 2.4.20-6 to 2.4.22.

This is on a Compaq desktop, and the 2.4.20-6 is what
i got as kernel from Redhat 9.0 CDs. I use GRUB
loader, and there is no other OS in the system.

Following are the steps i took, based on the
/usr/src/linux-2.4.20-6/README file.

Downloaded the linux-2.4.22.tar.gz file into /usr/src,
and untarred, which created /usr/src/linux-2.4.22.

# cd /usr/src/linux-2.4.22
# make config
# make dep
# make bzImage
# make modules
# make modules_install
# make install

No error came in any of these steps, and i could see
additional entries added for GRUB, and the boot image
appropriately copied into /boot

After these, when i reboot, i could see the additional
entry for 2.4.22 shown in GRUB menu. When i select
that and enter, following are some of the final
messages i get, saying kernel panic.

ds: no socket drivers loaded!
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

Not sure if i am missing some step, or missing to read
some already written document.

Your help will be appreciated.

Thanks,
Elwin.

If you want to use the vanilla kernel, you need to use "root=/dev/xxx"
instead "LABEL=/".

You can also use the mkinitrd that comes with redhat:

# cd /usr/src/linux-2.4.22

# make config
# make dep
# make bzImage
# make modules
# make modules_install
# cp System.map /boot/System.map-2.4.22
# cp arch/i386/boot/bzImage /boot/vmlinuz-2.4.22
# mkinitrd /boot/initrd-2.4.22.img 2.4.22

If you get errors, it will most likely be SCSI or something.

Try:

  --omit-raid-modules  or  --omit-scsi-modules.

man mkinitrd.
