A common I2C bus error is slave devices that have ended up in a state where Data (the data line) is low. Typically a master performs error recovery by clocking the Clock line until the Data line is high and then issuing a Start followed by a Stop.
Further explination of the problem is described at:

Does anyone have a Linux driver patch to perform the bus recovery by toggling the SCL line until SDA line is released again?
Thanks,
