Question Problem with upgrading Kernel 2.4.18

I try to update my linux kernel to 2.4.18 , I followed all the nornal steps,
everything looked fine, but when I used the new kernel to boot the system
error message showed :
VFS: can not mount the root fs 0308
my linux root is on hda8
I changed many options of the kernel, and I also usd " make oldconfig"
still got the same error message
( I use 20GB harddisk with LILO to control multisystem boot :
hda1: boot Fat
hda2: winXP NTFS
hda3: Win2000 NTFS
hda4: Backup NTFS
hda5: Backup NTFS
hda8: / ext3
hda9:/home ext3
hda10/usr ext3
hda11 /swap

Sounds like you have something enable in the kernel that should not be,

Is it using reiserfs?

I might be completely off - but do you have ext3 compiled in the kernel? As a module it wont work.
Also, do you got ext2 enabled, too?
I did build a kernel with reiserfs one time and took ext2 out. Didnt boot afterwards.

I really recommend going through the kernel config (make menuconfig is easy to use) and doing your own configuration. Especially if you are using a distros stock kernel as your current kernel.

What is strange to me is even if you didn't compile in ext3 support ext3 partitions should be mountable as ext2 however the journal will not function. I would go through the entire kernel config, and among other things, carefully check what file systems are compiled in.

Also, you are passing in root=/dev/hda8 right? Another thing to consider, if you have a off board of second IDE controller on your motherboard the device ids can change depending on the kernel. For instance, I have a Promise Ultra 100 card on my system and depending on kernel options my first drive can either be /dev/hda or /dev/hde. Double check that. If it has reversed it from what it was before then you need to turn on (or off as the case may be) Boot Off-board chipsets first in the ATA section of the kernel configuration.

I got the same error a while ago on a system that is dual booting
I udated the redhat kernel and I found that /etc/lilo.conf was incorrect

Also I ended up with a partition that would not mount

check lilo.conf

try tune2fs -j /dev/hda8
