unresolved symbols !!!

Hello all :

I have the following problem in inserting scheduler modules:
I have built the kernel with *all* the schedulers (sch_*) and *all* the
classifiers (cls_*) as modules. I have also enabled RNETLINK in .config.
When I do 'make modules' and 'make modules_install' everything is fine.
But once I reboot the machine with the newly built image and then try to
insert the modules using 'modprobe -a *' , 'depmod -a' or even 'insmod
(individual modules)', I get the "unresolved symbols" messages. I am left
clueless. The error messages are as follows :

/lib/modules/2.2.5-15/misc/sch_cbq.o: unresolved symbol qdisc_get_rtab
/lib/modules/2.2.5-15/misc/sch_cbq.o: unresolved symbol unregister_qdisc
/lib/modules/2.2.5-15/misc/sch_cbq.o: unresolved symbol qdisc_put_rtab
/lib/modules/2.2.5-15/misc/sch_cbq.o: unresolved symbol register_qdisc
/lib/modules/2.2.5-15/misc/sch_cbq.o: unresolved symbol pfifo_qdisc_ops
/lib/modules/2.2.5-15/misc/sch_cbq.o: unresolved symbol
/lib/modules/2.2.5-15/misc/sch_cbq.o: unresolved symbol

These are (almost) similar to all the scheduler modules.

I was successful in the above exercise with 2.2.1 kernel, but now I have
upgraded to 2.2.5 which has the said problem.

I would be very grateful to all the assistance or pointers. Thanks in
