Failed! So sensors-detect doesn't seem to think that this is a PCA9540, while it really is supposed to be. The problem is that there is no easy way to detect that chip. Do not run i2cdump on it, it won't work and will leave the chip in an undefined state (if it is a PCA9540, that is). I'd suggest you open the case and visually inspect your motherboard in search for a PCA chip. It would be very small (8 pins) and most likely located between the two CPU sockets. Also, while searching for info on your motherboard in my mail archives I found the following record: "BTW, the user has something strange with the other chip on the Gigabyte GA-7DPXDW+, a Winbond W83627HF. It was working fine, but after he scanned the SMBus (on which the LM90 is, but the W83627HF is *not*), the W83627HF partly stopped working. Fan speeds are still OK, but voltages and temperatures are dead (registers read $00 or $FF). Have you ever seen that before?" I have no other trace of the event, so I'm not sure if we ever understood what had gone on, nor whether the readings ever went back. There is probably no need to be afraid (that user probably just had bad luck, no relation with lm_sensors), but I thought I'd let you know, just in case.
