^^^^^
Wrong path -----------------------------------------------------|
That's an old ivtv module. Move it out of the way or get rid of it.
You may have to as root run:
# /sbin/depmod -a 2.6.18-164.9.1.el5
again after removing it.
You may also want to look for any other duplicate module names
under /lib/modules/2.6.18-164.9.1.el5/ and move the older ones out of
the way or remove them.
Regards,
Andy
