pcHDTV :: View topic - Error modprobing cx88-dvb on 2.6.11-1.27

pcaylor · Guest

I am having difficulty installing the 2.0 drivers on FC 3 with kernel 2.6.11-1.27_FC3smp. make & make install work fine and I am able to modprobe cx8800 without errors. However, when I try to modprobe cx88-dvb I get the following errors:

# /sbin/modprobe cx88-dvb
WARNING: Error inserting video_buf_dvb (/lib/modules/2.6.11-1.27_FC3smp/v4l2/video-buf-dvb.ko): Unknown symbol in module, or unknown parameter (see dmesg)

dmesg gives the following output:

I've done quite a bit of reading on this and it looks like the only others that had these errors were able to clear them up with a simple reboot. Unfortunately, I'm not so lucky. If anyone has some ideas on how to resolve this, I'd appreciate any assistance.

Thanks!

Look for duplicate modules under the module tree that match the modules in your driver directory.

The only copies of video-buf-dvb.ko or cx88-dvb.ko I have are the copies in /home/user/pcHDTV-2.0 and another set in the /lib/modules for the kernel version I running.

Any other suggestions?

Try running /sbin/depmod -e (as root) and see if there is anything reported there. Are you also compiling the latest DVB code from CVS or using what is already in the kernel? I ask because there is a module synchronization issue when compiling modules in multiple places.
That gives the same kind of error you are seeing.

depmod -e doesn't return anything.

I should be using the DVB drivers that were included in the kernel. (The kernel package is from atrpms)

I did notice that when I ran modprobe -v cx88-dvb it looks like there might be a conflict between some of the DVB drivers that are loading.

Any suggestions on how to get the correct set loaded? (Or for that matter, which is the correct set? I assume its .../drivers/media/dvb/ but I'm not that familar with v4l and dvb.

Thanks!

Ok Peter -
You got the correct modules loaded through some mechanism outside of your kernel. (Because they weren't in kernel 2.6.11) Assuming you installed using the "make install" script from the 2.0 drivers you won't be able to just remove the v4l directory. You will want to remove the duplicate modules from either place (to be safe I would remove the duplicates from v4l first, they are built from the 2.0 driver "make" and you can always make them again.). Then things should load for you.

Another option is to do an up2date on the kernel and update to 2.6.12 for FC3 which won't require you install the 2.0 drivers at all. The modules are already in the kernel tree in the correct locations. Try removing the duplicate modules first...

I upgraded my kernel to 2.6.12 and the DVB drivers worked perfectly. Now I just need a better antenna so I can tune something other than PAX TV.

Thanks for all your help!
