[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.

There is very similar (or same) problem on desktop Dell Studio XPS 8100.
See bug: https://bugzilla.kernel.org/show_bug.cgi?id=100121
In your long email is missing one important information: DMI information
about your machine. Can you run dmidecode and send output?
You were able to bisect problematic commit, are you able to do some
additional test and debug root of this issue?
In my opinion problem is in some SMM call, but without commenting code
which calling it, step by step and testing is not possible to decide...

Hi Pali,
Yes I can compile the kernel, yes I can debug this if you can suggest
possible fixes or kprintf that you would like added to get more information.
Sorry I missed the dmi info...

Hi Pali,
By the way I can now confirm that after several hours of use with the
"good" kernel that the processor fan flares up.. once.. then goes back
to normal speed. So it is entirely possible that the kernel change that
causes the Erratic fan behaviour has deep roots and that this commit is
not necessarily the one that introduced the problem but more like the
one that makes the problem very obvious!
Looking forward to working with you guys to fix this!
Peter.
