That is strange indeed. Can you reproduce this and then unload the
dme1737 module and run 'i2cdump 0 0x2e' and post the output?

That's possible. The Int-temp is the dme1737 internal temperature, not
the 'board' temperature. Depending on how hot the chip itself is this
temperature can be rather high.

There's not much that can be done wrong here. All the driver does is
convert from unsigned to signed. Sensors itself doesn't do any
conversion.
