does the patched kernel need a initrd in order to work?

hello

i tried to install a new kernel 2.4.32 patched with grsec 2.4.32

on a sarge debian distro with kernel version 2.4.27.

after having read and applied the quick start manual:

if i do not make an initrd.img-grsec2.4.32

grub can't find the patched kernel at (hd0,0)

if i make an initrd

there is a Oops 0002

kernel panic attempted to kill idle task

thanks

ps:sorry i m a french student who does not write english very well

It seems you're using Debian's facilities for compiling your kernel, aren't you? If so, try compiling by hand, that is:

Code: Select all
make menuconfig    ## you've already done this
make bzImage modules modules_install
cp arch/i386/boot/bzImage /boot/vmlinuz-blah
cp System.map /boot/System.map-blah
$EDITOR /boot/grub/menu.lst
reboot


Of course, you can turn initrd on or off if you want.
