[cpia] CPia driver hangs the computer?

[Jose Miguel Buenaposada Biencinto]

Hi!

I hope somebody knows what is happening ;). Well, I have a Zoom Cam USB
and I'm using it with the 2.2.14 kernel, the USB backport (from 2.3.50
kernel)
and the 1.0 CPia driver for linux. Well I'm developing a real time video
processing
application with it, using v4l and gtk+.

The problem is that sometimes the biprocessor box I'm ussing is
completly locked
when I'm running mi app with KDE (is this important?) and the only thing
I can do
is restart the computer (neither pings nor change to a text console
works).Of course,
my program maybe is completly wrong but I think maybe there is a problem
with the
USB stack or the CPIA driver. The kernel 2.2.16 with the corresponding
USB patch
will be better ?

Those are the last lines of the system log that I can read when the
system reboots:
