[1.] One line summary of the problem: Erratic fan speed and little control kernel 4.2
[2.] Full description of the problem/report: After upgrading to kernel 4.2 my CPU fan started speeding and slowing without good reason even when the PC is idle.
sensors shows: it8721-isa-0a10 Adapter: ISA adapter fan1: 1071 RPM (min = 13 RPM) fan2: 788 RPM (min = 46 RPM)
... dell_smm-virtual-0 Adapter: Virtual device Processor Fan: 1079 RPM Motherboard Fan: 794 RPM
To make the erratic behaviour start either wait for a few hours or: echo 200 > /sys/class/hwmon/hwmon3/pwm1 echo 70 > /sys/class/hwmon/hwmon3/pwm1
To stop erratic fan speed - reboot sometimes works.
This bug has been bisected to commit f989e55452c74b4f7b22c889b8ec9f1192aaeec4 : i8k: Add support for fan labels
I noticed that in the good kernel prior to commit f989e55452c74b4f7b22c889b8ec9f1192aaeec4 that the order of the fans in the it8721-isa-0a10 section of the sensor output is reversed. it8721-isa-0a10 Adapter: ISA adapter fan1: 965 RPM (min = 13 RPM) ***** good kernel has the Motherboard Fan first fan2: 1112 RPM (min = 21 RPM) ***** good kernel lists the Processor Fan second.
i8k-virtual-0 Adapter: Virtual device fan1: 1120 RPM **** good kernel has different fan numbering for the i8k-virtual-0 device! fan2: 972 RPM **** good kernel has different fan numbering for the i8k-virtual-0 device!
commit f989e55452c74b4f7b22c889b8ec9f1192aaeec4 : adds labels support for fans if SMM function with EAX register 0x03a3 reports it. This information was taken from DOS binary NBSVC.MDM.
Additionally this patch change detection of fan presence. Instead reading fan status now detection is based on new label SMM function. Dell DOS binary NBSVC.MDM is doing similar checks, so we should do that too.
This patch also remove I8K_FAN_LEFT and I8K_FAN_RIGHT usage from hwmon driver part because that names does not make sense anymore. So numeric constants are used instead. Original /proc/i8k ioctl part was not changed for compatibility reasons.
