multiple saa7130 chipsets problem
Hi
I'm using 8 x saa7130hl chipset based surveillance card and recently bought another one.
Just wanted to achieve 16 channels for cams recording.
Problem is that saa7134 module will only see eight integrals of card array 'card=x,x,x,x,x,x,x,x' and while i'm putting 'card=x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x' - dmesg will print
card: can only take 8 arguments
saa734: '69' invalid for parameter 'card'
Modprobing with 'only' eight parameters will result that saa714 will be try to autodetect chipsets, which is appraently ends with hang errors. Is there a siple hack to ovverride this behaviour ?

You could try modifying
#define SAA7134_MAXBOARDS 8
in linux/drivers/media/video/saa7134/saa7134.h and recompiling.

It did the trick :)
Now kernel seees two x eight channel cards, and i've '/dev/video*' from 0 to 15
Thanks
