modprobing ivtv-fb still segfaults.

I've already posted about this in http://ubuntuforums.org/showthread.php?t=568074
but will repeat it here as it is not specific to mythbuntu.

I've found this post at ivtv-dev
http://www.ivtvdriver.org/pipermail/...st/004988.html

According to the post on ivtv-devel the wrong ivtv-driver.h file is used when compiling the module. I found the following lines in ivtv/driver/makefile

ivtv-driver.h:
ifeq ($(wildcard $(KDIR)/include/config/kernel.release),)
@KVERNUM=`echo $(KVER) | sed 's/-.*//'`; \
echo "Kernel version number: $$KVERNUM" ; \
if [ "$$KVERNUM" = "2.6.22" -o "$$KVERNUM" = "2.6.22.1" ]; then \
cp -v ivtv-driver1.h ivtv-driver.h; \
else \
cp -v ivtv-driver2.h ivtv-driver.h; \
fi

And here you can see that in case of kernel version 2.6.22, the ivtv-driver1.h is used as ivtv-driver.h. But ivtv-driver1.h differs from the ivtv-driver used in the kernel. ivtv-driver2.h however does not differ from the one used in the kernel and in this case is the one that should be used.

The module is using the wrong header,

cheers
