I am running an older Compaq Presario 2600cl with Fedora 9 I am getting these messages. I update BIOS to most recent ( Nov, 2004 ) I have googled and worked this problem for several hours, but I am still not able to stop the messages every 2-4 seconds: Jul 31 17:13:37 sissy kernel: ACPI: Unable to turn cooling device [f7811f18] 'on' Jul 31 17:13:39 sissy kernel: w83627hf: Found W83697HF chip at 0x290 #This is where I restarted lm_sensors Jul 31 17:13:43 sissy kernel: ACPI: Unable to turn cooling device [f7811f18] 'on' Jul 31 17:13:49 sissy kernel: ACPI: Unable to turn cooling device [f7811f18] 'on': I modified the sensors3.conf as noted below; restarted lm_sensors chip "w83697hf-*" ignore temp1 ignore temp2 ignore fan1 label temp3 "CPU Temp" set temp1_type 1 # ? set temp2_type 1 # ? set temp1_max 51 set fan1_min 0 sensors cmd no longer shows values for temp1, temp2, fan1. OK but messages continue every 2 - 4 seconds.
