I see one bug clearly, and I'm pretty close to seeing the other one. But for tonight, I need sleep. In the meantime, please try this command as root, against the newer kernel, *after* you've done 'sensors -s': # i2cset -f 0 0x2d 0x5d 0x0e b Wait > 2 seconds for the hardware to update itself, then run 'sensors' again. I'm pretty sure you'll see the correct temps. Regards, -- Mark M.
