Partial success with CPiA on 2.3.13!

[R. Steven Rainwater]

I finally got my first frame grab that didn't crash the kernel
now that 2.3.13 is out! However, I can only get one frame. Any
attempt to grab after the first frame will cause a crash and
instant system reboot (not even an Oops! screen). The only way
to get another grab is to disconnect the camera, reboot, and
then reconnect the camera. I am using the command
 
	vidcat > /tmp/test.jpg

Here's the message log showing the device connect and the grab
that works:

On the second grab, it looks like the process completes but
the reboot occurs before the info can be logged or the file
saved (not absolutely sure of that though as it all happens
so fast!).
