Hi Richard,

today zypper updated my kernel from 2.6.34-12-desktop to 2.6.34.7-0.7-desktop, now I have problems with the modules dvb_bt8xx and bt878.
Note that there are many intermediate versions available between these two. It would be interesting to test them, to find out with which exact package version the problem was introduced.
Ok, I'll find the exact version.
The kernel hangs while loading dvb_bt8xx:
I presume that by "hangs" you mean progress is very slow for some time, but it doesn't actually hang forever?
It hangs completely for 30 seconds per unknown symbol.
[ 2.765243] saa7134[0] Tuner type is 38 [ 32.616021] dvb_bt8xx: gave up waiting for init of module bt878.

or while loading bt878:

All 3 symbols are indeed supposed to be exported by module bttv. What happens if you try: # modprobe bttv ?
This works fine. Maybe it is a race while loading saa7134 and bttv?
If more symbols are missing, please follow the trail of modules, until you get a different type of error, or a cycle.
This happens always after a reboot and sometimes after a shutdown. With 2.6.34-12-desktop I've had no problems with these modules.
Did you change anything to your hardware recently? In particular, was the SAA713x-based card already present before?
No, this is my rock solid desktop pc. I did not change anything. I can reproduce the problem by downgrading the kernel and updating it again...
