Hi Peter! Thank you for information! Are you able to try to call that
function on some old kernel (e.g. 3.12 or 3.14) to verify that it is
caused only and only by that function?
I have tried to use my old 3.19.0 kernel that did not have the problem
but now

I have just tested removing i8k_get_fan_type() function from the
dell-smm-hwmon driver in the kernel on my Dell Inspiron 580 and the fan
speed problem goes away. My patch simply replaced fan_type with
fan_status in i8k_init_hwmon and used the index as the type in
i8k_hwmon_show_fan_label

his 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!

Hi Pali,
Yes I can compile the kernel, yes I can debug this

[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:
