I have Fedora Core 1 installed and now I am trying to build a new kernel using the same kernel source files as the host uses.
After I have the kernel compiled I copy the bzImage to /boot and rename it to kernel_mybld. And I come to modify the /etc/grub.conf. Before my changing it is like this,
default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title Fedora Core (2.4.22-1.2115.nptl)
root (hd0,0)
kernel /vmlinuz-2.4.22-1.2115.nptl ro root=LABEL=/12 ide=nodma rhgb
initrd /initrd-2.4.22-1.2115.nptl.imgThen what I do is basically add another entry like this,
title mybld root (hd0,0) kernel /kernel_mybld ro root=/dev/hda1 LABEL=/ ide=nodma rhgb initrd /initrd-2.4.22-1.2115.nptl.img
The idea is to test the kernel I just built. As you can see really the only change from the 2nd entry to the first one is that I use the kernel I just built.
Another change is "root=LABEL=/12" ==> "root=/dev/hda1 LABEL=/" because the former one did not work and I do not understand it.
But in rebooting and select entry 2, I get an error,
VFS: mounted root (ext2 file system) readonly Freeing unused kernel memory: 88K Warning: unable to open an initial console Kernel panic: No init found. Try passing init= option to kernel
In config the kernel I did enable the EXT2 FS.
If I go back to boot the 1st entry, it is still OK. So looks like the new kernel has some problem, but I have no clue of it.
Any suggestion?
