viafb-camera: Funky IRQ

[Alan Jhonn Aguiar Schwyn]

With the kernel 3.2.. I have a problem with the camera.When starts (with any program, or directly with pygame) the computer freezes.Never can see the errors (freezes immediatly)Now, with kernel 3.5.0-17 works (since 3.5..).I think that are a problem with that kernel.. 
Which image are using in the XO, which kernel it has?
