Hi,
I am trying to compile kernel 2.6.30.2 on slackware 13. Everything went fine. Finally when I tried to boot from new kernel I am getting error message like 'kernel panic: VFS: unable to mount root fs on hda1'. My /etc/lilo.conf is like this:
image = /boot/vmlinuz
root = /dev/hda1
label = Linux
read-only
image = /boot/bzImage-2.6.30.2
root = /dev/hda1
label = Linux-test
read-only
My first os is booting correctly. I have compiled second one with ext3 support and my file system is ext3. Then I created initrd for ext3 and added in /etc/lilo.conf. Now its booting. But its not showing files in /dev/hda1. Can any one tell where I am going wrong.

Can you output of dmesg command.

Thanks

Thanks for your replay. My problem is I cant save output of dmesg(in compiled kernel) since I am working on ram fs(initrd). I have no way to mount persistent fs. But by seeing dmesg output I can tell you that my kernel is not switching back to /dev/hda1 from initrd.
Please tell me why it is happening like this.
