I've done some cursory debugging and it the problem is related to
running two saa7134 cards, one with and one without a 6752.
Summary:
BMK MPEG2 registers
/dev/video0 [v4l2]
/dev/video1 [ts]
FLY Video 3000 registers
/dev/video2 [v4l2]
When /dev/video1 is opened the kernel exception occurs. I've tried
juggling the cards around and the fault sticks with the 'ts' device. The
error occurs when the following line is invoked:
err = file->f_op->open(inode,file);
(line 130 from videodev.c)
The currently solution to this problem is I've rebuilt the saa7134.ko
with the 'ts' device creation removed. At least now I can access the
frame grabbers - A kludge of a work around.
Another issue I've found (not specifically related but obscure) is that
if the driver is loaded but the wrong card ref # is given (ref # for an
BMK MPEX) then a 'ts' device is registered even though the card has no
ts hardware. Similarly if an MPEX card is loaded with a ref # (ref # for
an non-MPEG2 card) then the 'ts' device is not created but the saa6752hs
is deteced on the i2c bus.
