Hi all,

I could create bzImage (2.4.26)in Slackware using make xconfig,make bzImage.This bzImage works fine.When i do this in fedora core 1(Its own kernel,I forgot the kernel version) and enable ext2,ext3 filesystems, on reboot I get the message 'Could not mount root fs'.How do i debug this.

Thanks in advance

Did you build ext2 support into the kernel, or leave them as modules?

Yes i did build ext2 support into kernel

Prepare an initial ramdisk image for the newly complied kernel and modify grubs config file to include it as well.

#mkinitrd /boot/initrd-kernel-version.img kernelversion
eg
#mkinitrd /boot/initrd-2.6.11.img 2.6.11

in grubs config something like this:

kernel /boot/vmlinuz-2.6.11 ro root=/dev/hd??
initrd /boot/initrd-2.6.11.img

Also make sure you are passing the correct root parameter to the kernel.
eg root=/dev/hda2 if / is in the second hdd partition.

Basically you may not need initrd image if ext2/ext3 was built into the kernel and not as modules but there are other things that may need it.
