[PLUG] kernel 2.4.27 problem xubuntu

[Udayraj]

Hello List

I need to use kernel 2.4.27 on my xubuntu installation. I have
installed the kernel using synaptic.
My problem is when I try to boot using the kernel from grub it gives a
"VFS: unable to mount root on 0:0" kernel panic error

Below are the partial contents of my menu.lst file. the commented line
is my try to solve the problem. /dev/hda8 is an ext3 partition
