[linux-dvb] Kernel Oops with vanilla 2.6.12.3

Hello,

I'm running a vanilla 2.6.12.3 kernel. This is the second time I see a 
kernel oops in recent times, but this time I was lucky enough that 
something ended in my syslog, see the attachment.

My hardware are 1 old ff siemens card and 2 new nova-t budget cards 
(conexant revision). I'm running a plain Debian with vdr 1.3.17 from the 
e-tobi vdrdevel binary distribution (package version 1.3.17-9).

Let me know if you need more log or system data.

Thanks,

Hanno
