viafb-camera: Funky IRQ

These kernel messages seem normal to me, in that they were present in
manufacturing tests and apparently did not affect the Sugar Record

I don't think the "ffplay -loglevel 7" did anything to change these
messages, since they are emitted by the kernel and not ffplay.

I think you may need to diagnose the freeze a bit further.  Is the
freeze only of your application, or is the freeze also affecting
keyboard, touchpad and other things?

If the freeze is affecting more than the application, I suggest you
attach a serial console and look for kernel output there.  Perhaps you
have found a way to panic the kernel.
