Late follow up - but i only _now_ have 2 of these card. Situation now
is that it doesn't oops anymore - however its not fixed in the end. 

Problem which still exists: When one card is recording in vdr, the
second card possibly doesnt get a lock anymore. if second "receiver" is
live tv, switching back and forward a couple of times makes tuning
possible in the end, but it can also break recording. 

So from overall picture its seems there are ressources which are not
guarded against use at multiple devices. The fix for the oops has only
fixed the immediate crash but did not solve the common use of
ressources. 

Can you let me know how to start tracking this down ? Beside me i know
a couple of others having more than one of these cards, and - if its
the best/easiest way i could also imagine to organize temporary 2 of
this cards for a developer able to fix it.
