Kernel build does not post modules

[Hausi]

Hi, since a few weeks I seem to unable to build modularized kernels. I am running Ubuntu 8.10 and use the current kernel source (linux-2.6.27.9.tar.bz2). When compiling the kernel I get this message after the 'make modules':

<snip>
CC [M] net/x25/x25_proc.o
CC [M] net/x25/x25_forward.o
CC [M] net/x25/sysctl_net_x25.o
CC [M] net/netfilter/xt_state.o
CC [M] net/netfilter/xt_statistic.o

CC [M] net/netfilter/xt_u32.o
LD [M] net/netfilter/nf_conntrack.o
Building modules, stage 2.
MODPOST 0 modules
<snip>

so there are compiled modules which do not get installed with 'make modules_install'

any help appreciated
thanks

update & reply to my own post:

today I tried (dont know why) to do something different:

sudo make bzImage && sudo make modules && sudo make modules_install

this _worked_

when I do a sudo -s and then compile I get MODPOST 0 modules as per my firts post

this is very strange and I would like to hear an explanation...
