Hi!

I tried to capture 1.2Mpix images, then scale them down to 800x600
using hardware... and results were  kernel dying.

[12552.400512] Hardware name: Nokia RX-51 board

I did more experiments before, and usually it does not end like
this. Usually, when I set up capture with greater resolution than cca
800x600, I get 4 copies of image above each other.

If you know how to get images with greater resolution, let me know.

Best regards,
									Pavel
