Hi Hans, I compiled and tested the driver. Here is the kernel log at startup : Dec 15 23:07:46 xxxx kernel: [82199.773523] f71882fg: Found f8000 chip at 0xa00, revision 41 Dec 15 23:07:46 xxxx kernel: [82199.773742] f71882fg f71882fg.2560: Fan: 1 is in duty-cycle mode Dec 15 23:07:46 xxxx kernel: [82199.773745] f71882fg f71882fg.2560: Fan: 2 is in duty-cycle mode Dec 15 23:07:46 xxxx kernel: [82199.773748] f71882fg f71882fg.2560: Fan: 3 is in duty-cycle mode Here is the "sensors" (sensors version 3.0.2 with libsensors version 3.0.2) output : f8000-isa-0a00 Adapter: ISA adapter in0: +1.68 V in1: +1.67 V in2: +1.64 V fan1: 1486 RPM fan2: 894 RPM fan3: 0 RPM ALARM fan4: 34464 RPM temp1: +46.0?C (high = +70.0?C, hyst = +60.0?C) temp2: +41.0?C (high = +100.0?C, hyst = +85.0?C) sensor = Intel PECI temp3: +40.0?C (high = +100.0?C, hyst = +85.0?C) There are only two fans on my computer. "fan3: 0 RPM ALARM " seems alright as there is no fan. "fan4: 34464 RPM" is a bit strange Voltage indication seems to be divided by two. I guess sensors3.conf should be modified for f8000 chip.
