I don't use "make zImage", but are you sure you're booting the new kernel?
Your /etc/lilo.conf probably points to /boot/vmlinuz-2.0.27 or something
like that, but your new kernel might not be there. Do an "ls -l" in the
/boot directory and check the date of the kernel that you're booting from
lilo. If it is older than it ought to be considering that you just built
a kernel, that's the old one. The new kernel is
/usr/src/linux/arch/i386/boot/zImage
and you have to put it in /boot yourself and make sure /etc/lilo.conf
points to it correctly. Here's how I'd do it:
In /boot, change the name of your original kernel (vmlinuz-2.0.27
probably) to vmlinuz.orig, and copy your new zImage to /boot, naming it
/boot/vmlinuz-2.0.27 (or whatever is appropriate). Make sure that
/boot/vmlinuz, if it's there and is a symlink, points to your new kernel.
Now edit /etc/lilo.conf, make sure the "linux" section refers properly to
your new kernel, and and put a new section in there to boot your old
kernel with a tag like "old" or something, in case the new kernel is
tweaked somehow. NOW run lilo and reboot and see what happens.
