Hi Sandeep, A few extra hints and requests. I have been adding a preliminary pc87366 section to sensors.conf.eg. Please manually copy to /etc/sensors.conf and test. There are a couple ignore lines you should uncomment. I have also been updating the driver so that it honors the "external vref" configuration bit. Your voltages should report slightly higher values now (+2%). Vsb and AVdd have supposedly a value of +3.3V and that's what sensors should report. Please try setting voltage limits (sensors -s should do for Vsb and AVdd) and report how it works. I'd also like you to run the following set of dumps and send me back the output files, so that I can use this for reference while working on the driver. I have a similar set for a second PC87366 owner (completely different motherboard) and comparing results will be useful. Please dump at a time your chipset is working at best. isadump -f 0xecc0 16 > pc87366-fans.dump isadump -f 0xecd0 16 0 > pc87366-in0.dump isadump -f 0xecd0 16 1 > pc87366-in1.dump isadump -f 0xecd0 16 2 > pc87366-in2.dump isadump -f 0xecd0 16 3 > pc87366-in3.dump isadump -f 0xecd0 16 4 > pc87366-in4.dump isadump -f 0xecd0 16 5 > pc87366-in5.dump isadump -f 0xecd0 16 6 > pc87366-in6.dump isadump -f 0xecd0 16 7 > pc87366-in7.dump isadump -f 0xecd0 16 8 > pc87366-in8.dump isadump -f 0xecd0 16 9 > pc87366-in9.dump isadump -f 0xecd0 16 10 > pc87366-in10.dump isadump -f 0xecd0 16 11 > pc87366-in11.dump isadump -f 0xecd0 16 12 > pc87366-in12.dump isadump -f 0xecd0 16 13 > pc87366-in13.dump isadump -f 0xecf0 16 0 > pc87366-temp1.dump isadump -f 0xecf0 16 1 > pc87366-temp2.dump isadump -f 0xecf0 16 2 > pc87366-temp3.dump Thanks. -- Jean Delvare http://khali.linux-fr.org/
