Well, we're on a different platform and we don't use BLOCK_DATA transfers but single byte instructions. You still think it's related?

I have no idea, I just wanted to bring it to your attention, in case it sparked something. The original code uses i2c_smbus_write_byte_data, but the new code uses i2c_transfer(). Maybe that function is smarter about handling the I2C bus?
