OK, this rules out a user-space issue. The problem must be either at
the hardware level or in the lm85 driver.
Please unload the lm85 driver temporarily, load the i2c-dev driver, and
provide the output of the following command:
i2cdump 0 0x2e
This will dump all the device registers. I will then check against the
datasheet and see if I spot anything.
