Title:
  erratic fan speed and little control kernel 4.2

Status in linux package in Ubuntu:
  Triaged

Bug description:
  After upgrading to Ubuntu 15.10 my CPU fan started speeding and
  slowing without good reason even when the PC is idle.

  This has been bisected to commit f989e55452c74b4f7b22c889b8ec9f1192aaeec4 :
  i8k: Add support for fan labels

  This patch 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 presece. 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.

  WORKAROUND: Shutdown. After it cools down for a while, turn it on.

  Tried intel_pstate but it is not supported for some reason on my
  machine ie the following does not work and I am left with driver:
  acpi-cpufreq

  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_pstate=enable"

  Could not see ACPI Thermal Zones reported in dmesg

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I have just upgraded to Ubuntu 15.10 and almost immediately my CPU fan
  started speeding and slowing without good reason even when the PC is
  idle.

  I tried various things but then found that if I leave the computer off
  for a long time and let everything cool down then when I boot from
  cold the CPU fan is stable.

  To test my theory of cold start out I then ran
  sudo cpupower frequency-set -g powersave
  followed by
  sudo cpupower frequency-set -g ondemand

  The final mode is the initial mode.  Almost immediately as soon as I
  moved to powersave mode the erratic fan speed started.  It did not
  stop when I returned to ondemand.

  Temp fix for this behaviour is - go and have a cup of coffee and let
  the computer cool down when you restart: shutdown then start from
  cold.

 1a131ca1de7a84cf3827c418ee5971b493c6f23f then the fan is well behaved..

ie echo 200 > /sys/class/hwmon/hwmon3/pwm1 
 The fan speed builds up gradually and results in a reasonable constant fan 
speed fan1:2207 RPM

echo 180 > /sys/class/hwmon/hwmon3/pwm1 
The fan speed is reasonably constant at fan1:1118 RPM
 
Note in both bad and good kernel the fan speed is not linear with the value 
sent to pwm1, rather a step change at about 192 from slow to fast.

In the good kernel the fan speed is rock solid constant.. I could not
seem to get the fan to get faster than 2207 RPM

In the bad kernel the fan speed is always varying as indicated above.
When configured with echo 200 >  /sys/class/hwmon/hwmon3/pwm1  the fan
speed is always varying about a high value and with echo 180 >
/sys/class/hwmon/hwmon3/pwm1 the fan speed is always varying about a low
value.  The range of fan speeds seems larger with the bad kernel (3000
-> 300) as you can see from the comment above.


Noticed that in the good kernel the virtual device seems to report the fans in 
the opposite order:
$ sensors

Vbat: +3.02 V  
fan1: 965 RPM  (min =   13 RPM)
fan2:1112 RPM  (min =   21 RPM)
temp1:-78.0°C  (low  = +55.0°C, high = -68.0°C)  sensor = thermal diode
temp2: -8.0°C  (low  = -57.0°C, high = -93.0°C)  sensor = thermistor
temp3:-71.0°C  (low  = -77.0°C, high = -49.0°C)  sensor = Intel PECI
intrusion0:  ALARM

i8k-virtual-0
Adapter: Virtual device
fan1:1120 RPM
fan2: 972 RPM

Notice that in comment #16 the fan speeds are in the same order... apart
from the label change.

So with the good kernel it seems that the virtual device thinks fan1 is
the CPU fan and the ISA adapter thinks that fan2 is the CPU fan.

With the bad kernel it seems that the virtual device thinks that the CPU
fan is called Processor Fan and the ISA adapter thinks that the fan1 is
the CPU fan.

Seems to me like someone has switched some labels about!  Perhaps by
"correcting the labels" something else has gone wrong!  Perhaps ISA
adapter needs to think that fan2 is the CPU fan for some reason!

Anyway thats about all I can see is different from a quick review of the
sensor command output.

2015-11-28 Thread Peter Saunderson 
Small update... still using 1a131ca1de7a84cf3827c418ee5971b493c6f23f

CPU fan just shot up to high revs and then back down to low revs after several 
hours of use.  Just one shot no more high revs so very different 
characteristics to the bad kernel but still interesting.
Core 0:   +31.0°C  (high = +83.0°C, crit = +99.0°C)
Core 1:   +29.0°C  (high = +83.0°C, crit = +99.0°C)
Core 2:   +30.0°C  (high = +83.0°C, crit = +99.0°C)
Core 3:   +28.0°C  (high = +83.0°C, crit = +99.0°C)

So not due to core temperatures... only happened that once so far.  I
will keep using this kernel and see if it happens again.

Ubuntu-4.2.0-18.22 Ubuntu-3.19.0-20.20 so I will have a go first at

[Kernel-packages] [Bug 1514052] Re: erratic fan speed and little control kernel 4.2

2015-11-24 Thread Peter Saunderson 
Ok so I might have a bit of time to start this... in summary I have
already on my machine kernel 3.19.0-31-generic (last good version before
my update) kernel 4.2.0-17-generic (bad version installed with wily)

If I understand the basic process (from reading
https://wiki.ubuntu.com/Kernel/KernelBisection) I am to clone
git://kernel.ubuntu.com/ubuntu/ubuntu-wily.git and look for a bad commit
prior to kernel version 4.2.0-17 and after kernel version 3.19.0

starting with something like:
git bisect start Ubuntu-4.2.0-17.20 Ubuntu-3.19.0-22.22

I am guessing from the bisect work done in
https://bugzilla.kernel.org/show_bug.cgi?id=100121#c29 that this is
likely to be near f989e55452c74b4f7b22c889b8ec9f1192aaeec4... but I will
find out!

Yuriy Vidineev, you need to use the default Ubuntu kernel (not the third
party mainline one).

Hello Christopher,

Unfortunately I can't do it for now:

"The problem cannot be reported:
This is not an official Ubuntu package. Please remove any third party package 
and try again."

I use 4.3.0-040300-generic.
Looks like simplest way to do it for me - download 16.04 daily build and test 
on it. I'll try it soon
BTW rmmod dell_smm_hwmon fixes problem for me

Hi,

I've tried to use "ubuntu-bug linux", It open my browser, I login but I
don't know what to do after.

It says "no similar bug reports were found", must I create one new?

sorry should have said

to stop itto stop it
echo 200 > /sys/class/hwmon/hwmon3/pwm1
echo 70 > /sys/class/hwmon/hwmon3/pwm1

reboot
before the reboot cpu fan is slow but erratic
whilst the reboot the cpu fan goes up to max then stops when linux unloaded.

[Kernel-packages] [Bug 1514052] Re: erratic fan speed and little control kernel 4.2

2015-11-12 Thread Peter Saunderson 
Just tried out the kernel as per instructions

Linux HomeMegaUbuntu 4.3.0-040300-generic #201511020949 SMP Mon Nov 2
14:50:44 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

echo 200 > /sys/class/hwmon/hwmon3/pwm1
echo 70 > /sys/class/hwmon/hwmon3/pwm1

results in the erratic fan speed.

if no erratic behaviour wait for a few hours (seems to be about 4
-5hours) and the erratic fan behaviour starts.

to stop it 
echo 200 > /sys/class/hwmon/hwmon3/pwm1
echo 70 > /sys/class/hwmon/hwmon3/pwm1

seems to work for me for a few hours before it starts up again.

Interesting that

echo 200 > /sys/class/hwmon/hwmon3/pwm1

results in high CPU fan speed with slow changes in erratic fan (as shown
above) superimposed on top of high fan speed.

  I have just upgraded to Ubuntu 15.10 and almost immediately my CPU fan

  To test my theory of cold start out I then ran

  The final mode is the initial mode.  Almost immediately as soon as I
  moved to powersave mode the erratic fan speed started.  It did not

2015-11-12 Thread Christopher M. Penalver 
Peter Saunderson, the next step is to fully commit bisect from kernel
3.19 to 4.2 in order to identify the last good kernel commit, followed
immediately by the first bad one. This will allow for a more expedited
analysis of the root cause of your issue. Could you please do this
following https://wiki.ubuntu.com/Kernel/KernelBisection ?

Please note, finding adjacent kernel versions is not fully commit
bisecting.

Thank you for your understanding.

2015-11-10 Thread Benjamin 
The issue remains using the kernel 4.3.0 on my Dell Studio XPS 8000

This issue came when i upgraded My Ubuntu from vivid to wily so it
worked well on kernels 3.19.*

I have even done a fresh install of wily from the official ISO to be
sure it wasn't a configuration issue.

Title:
  erratic fan speed and little control kernel 4.2

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I have just upgraded to Ubuntu 15.10 and almost immediately my CPU fan
  started speeding and slowing without good reason even when the PC is
  idle.

  I tried various things but then found that if I leave the computer off
  for a long time and let everything cool down then when I boot from
  cold the CPU fan is stable.

  To test my theory of cold start out I then ran
  sudo cpupower frequency-set -g powersave
  followed by
  sudo cpupower frequency-set -g ondemand

  The final mode is the initial mode.  Almost immediately as soon as I
  moved to powersave mode the erratic fan speed started.  It did not
  stop when I returned to ondemand.

  Temp fix for this behaviour is - go and have a cup of coffee and let
  the computer cool down when you restart: shutdown then start from
  cold.

[Kernel-packages] [Bug 1514052] Re: erratic fan speed and little control kernel 4.2

2015-11-09 Thread Joseph Salisbury 
Does this issue go away if you boot back into the prior kernel version?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.3 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.

[Kernel-packages] [Bug 1514052] Re: erratic fan speed and little control kernel 4.2

2015-11-08 Thread Benjamin 
Since "dell-smm-hwmon" seems to be an alias of the i8k module, and based
on the solution from the #100121 of the kernel bug tracker, blacklist
"dell-smm-hwmon" resolved the issue at least on my Dell Studio XPS 8000.
I tried many hard reboots to confirm this.

However i don't really know this module and can't say if blacklisting it
is free of side effects.

i'd argue that this module concerns DELL laptops as it's modinfo
description suggests but my DELL studio XpS 8000 is a desktop, not a
laptop.

Title:
  erratic fan speed and little control kernel 4.2

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I have just upgraded to Ubuntu 15.10 and almost immediately my CPU fan
  started speeding and slowing without good reason even when the PC is
  idle.

  I tried various things but then found that if I leave the computer off
  for a long time and let everything cool down then when I boot from
  cold the CPU fan is stable.

  To test my theory of cold start out I then ran
  sudo cpupower frequency-set -g powersave
  followed by
  sudo cpupower frequency-set -g ondemand

  The final mode is the initial mode.  Almost immediately as soon as I
  moved to powersave mode the erratic fan speed started.  It did not
  stop when I returned to ondemand.

  Temp fix for this behaviour is - go and have a cup of coffee and let
  the computer cool down when you restart: shutdown then start from
  cold.
