I think i got the first defective unit

My d3 runs for about an hour, when this error come up:

Sep 20 21:03:33 (none) local0.err cgminer[374]: read_temp_func: can't read all sensor's temperature, close PIC and need reboot!!!


I reconnected all cables. But this changed nothing. Error comes up and blocks the machine. Does anybody have a solution for that?

Thanks in advance
