Hi Andy,

Can you give me a help how I can disable MSI ? Is it possible via module 
parameter in /etc/modprobe.d or do I have to change the source ? I did not 
find "MSI" inside.

I downloaded v4l-dvb with

  hg clone http://linuxtv.org/hg/v4l-dvb

and would like to generate a DKMS build.

Frank

Maybe this helps for more diagnosis:
