However, if you provide a few register dumps, I can double check if the chip is in an unexpected state. # rmmod it87 # isadump -k 0x87,0x01,0x55,0x55 0x2e 0x2f 0x07 # isadump 0x295 0x296 # modprobe it87 With these two register dumps I should be able to check if fan4_input is supposed to be enabled or disabled. -- Jean Delvare http://jdelvare.nerim.net/wishlist.html _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
