This is what I use when I create kernel module:
-------------------------------------------------------------------------
KERNELSOURCE=/home/mulyadi/kernel-ck/linux-2.6.11.1/
obj-m += newbies.o
default:
make -C ${KERNELSOURCE} SUBDIRS=`pwd` modules
-------------------------------------------------------------------------
I am not sure what "M" means, so try to replace it with "SUBDIRS".
SUBDIRS should be pointed to the directory which contains your kernel
module's source code.
Another thing is, are you sure "/lib/modules/$(shell uname -r)/build"
contains the correct kernel source and it is compiled 100% identical
with current running kernel. You must remember, even though it points
to correct subdirectory name, that doesn't neccessarily means the
kernel source configured inside the "./build" directory is 100%
identical with the running kernel. So please re-check it.
As always, there is -f (force) option to force the module loading... but
fixing the problem's root should be your #1 priority.
Good luck...
regards
Mulyadi
