Compiling Kernel

Hi all, I'm trying to compile my own kernel to see if I can get my own drivers installed, but making the kernel gives me the following error:

root@armoury:/usr/src/linux# make
  CALL    scripts/checksyscalls.sh
  DESCEND  objtool
  CHK     include/generated/compile.h
  GEN     lib/oid_registry_data.c

  CC [M]  lib/oid_registry.o
Kernel: arch/x86/boot/bzImage is ready  (#1)
  Building modules, stage 2.

make[1]: *** [scripts/Makefile.modpost:92: __modpost] Error 1
make: *** [Makefile:1237: modules] Error 2

All I know about this driver is that it has something to do with "multiple devices", in that I believe it's used for RAID, meaning that I'm not sure I can get away with disabling it in the .config and still have a fully working system.

Any ideas?
