I hope they've been of some help. I've just checkout latest svn (revision 56) and I tried it with the same result.

# cat /var/log/kern.log | tail -1

I find strange I'm not able to get it run while some months ago i did it. May you suggest something to try.

Hey, do you know about this bug http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=428587 ?

If that is the cause, simply calling /sbin/insmod instead of insmod should work fine.

Indeed insmod was affected from the bug you mentioned. But now I get this new error:

root@bee:/usr/src/syntekdriver/trunk/driver# /sbin/insmod ./stk11xx.ko
insmod: error inserting './stk11xx.ko': -1 Unknown symbol in module

Can you post your kernel logs ?

If I don't load the videodev module, I have (as you) :
[root@Dahlia driver]$ insmod stk11xx.ko
insmod: error inserting './stk11xx.ko': -1 Unknown symbol in module

and in my kernel logs :
stk11xx: Unknown symbol video_devdata
stk11xx: Unknown symbol video_unregister_device
stk11xx: Unknown symbol video_device_alloc
stk11xx: Unknown symbol video_register_device
stk11xx: Unknown symbol video_device_release

So, can you post your kernel logs... and no only one line !

By sample :
# cat /var/log/kern.log | tail -1
Sep 18 10:08:31 bee kernel: insmod[18236]: segfault at 0000000000000000
rip 00002baa3f6871d9 rsp 00007fff6b6b8f60 error 4

I can't help you...

...you have some reason. The message confused and I missed the duty. Anyhow, here we are:

Thank's to check two points :

1°/ Your kernel has to be compiled with the options : CONFIG_VIDEO_V4L2 and CONFIG_VIDEO_V4L1_COMPAT

2°/ You have to compile the module with the same version of headers that your kernel.
>> disagrees about version of symbol video_register_device
obviewsly, the stk11xx module isn't compiled with the good version !

The checks are positive:

root@bee:/boot# grep CONFIG_VIDEO_V4L2 config-2.6.22-bee
CONFIG_VIDEO_V4L2=y
root@bee:/boot# grep CONFIG_VIDEO_V4L1_COMPAT config-2.6.22-bee
CONFIG_VIDEO_V4L1_COMPAT=y

Speaking about the kernel, it is a debian-way compiled by myself.

Makefile.standalone points to the /lib/modules/2.6.22-bee and /usr/src/linux-source-2.6.22 and compiles a module which reports the 'Unknown symbol' errors. As a further try I've installed the linux-headers-2.6.22-bee package and re-ran make -f Makefile.standalone clean && make -f Makefile.standalone driver. That showed some problem in pointing to the correct paths so I made some symlinks where appropriate. So I got the new compiled but with the same errors.

Recently I've checkout from linuxtv's mercurial repository the v4l-dvb-experimental to compile kernel support for a dvb-t usb dongle which I accomplished succesfully.

I'll wait for the next vannilla kernel.

seems the problem is within the Makefile.
ctags is called with lack of args.
