The above is incompatible with spd5118 devices; See [1] for details. I don't immediately see why that would cause the i2c bus to lock up, but even if it didn't lock up the bus I don't see a means to get this to work. It is still puzzling that reading the i2c data using i2cdump fails. The spd5118 driver should not even probe if that is the case. Maybe Armin has an idea.
