As far as I can tell the I2C bus driver just asks for it's interrupt and uses it, so by setting each bus to it's GIC interrupt line (instead of the line from the I2C interrupt controller like in the AST2500), the I2C driver receives the correct interrupt.

ok. I am seeing this from the I2C model side and that is where the 
problem must be. I will dig in QEMU.

Thanks,
