This dmesg output has now been generated without being attached to the charger and restarting.

I have also reset phone to defaults and updated firmware from 2009.41.13 to 2009.42.11 I believe they were. It still acts the same.

I thought I'd edit this post and add a file of the output instead as the code box and multiple posts was messy. Also I don't think my last output was too good - it seemed like a software restart from something to do with the charger plugged in. But anyway, any ideas would be gratefully accepted.

I have noticed the output mentions...
Am I just drawn to this because of the i2c part? I don't know if that is related to the transmitter or just something with the processor etc. Anyway, I obviously don't know enough so I'll stop babbling now!
