RE: [LINUX-KERNEL] Problem loading any custom driver

Here is a makefile
# Makefile for the Los Angeles PCI Adapter
# This file supports Red Hat Linux kernel 2.6(included) and above
HPATH := /usr/src/kernels/2.6.9-34.EL-i686/include
CFLAGS = -I$(HPATH) -Wall -O2 -fomit-frame-pointer -c

obj-m += atf_host.o

Our group does not have ability to put files for outside access.
Can you specify what parts of the code you need me to attach?
Im not familiar with rules, is it allowed to attach source files?

you forgot to put a URL to your source code.......

however it strongly points towards a broken Makefile on your side.... if
we'd have that URL I could say for sure ..
