recomiling the kernel

[Patrick O. Coffey]

Hi,

  I noticed a few things in the list of what you did, after executing
make oldconfig, I believe you need "make bzImage modules" which will
build the kernel image and the modules for that image. Also you need to
make an initrd.img file for your new kernel using this command
"/sbin/mkinitrd /boot/initrd-2.6.5-1.358-custom.img 2.6.5-1.358" This
will create a new initrd.img file called initrd-2.6.5-1.358.img in the
/boot directory. The second part of the mkinitrd command "...
2.6.5-1.358" is pointing to the 2.6.5-1.358 directory containing your
modules for the new kernel in /lib/module. Then edit your grub.conf file
to reflect the new initrd.img file and try rebooting. Anyway this worked
for me, if I haven't explained this well feel free to let me know. HTH.
