system hung while loading streams.ko

hi all,

        I am trying to compile LiS-2.18 (downloaded from gcom.com)  on,
Redhat Enterprise Linux WS release 4 ( Nahant Update 2)  with kernel version
2.6.9-16.EL .

       I'm able to compile LiS but facing a problem while loading streams.ko
.
Whenever i tried to load streams.ko using either,

    insmod /lib/modules/`uname -r`/streams.ko  or
    modprobe streams.ko
the system is going to hang.

Can I have any solution to overcome this problem? If possible, let me know
why this problem was arised?

regards,
kishore,packetware.
