postadelmaga (postadelmaga),
it is going to be very clarifying if you can post the results of the
command "./probe_i8k_calls_time" here.
It seems that changing fan speed in some models is a slow call under the
very basic call in i8k kernel module.
If so in your system, nothing can avoid the lag:
this bug looks more generic and it is basically the same issue

please reopen the main bug and follow up that one

Ok I found another workaround for the fan speed:
- watch echo 255 > /sys/class/hwmon/hwmon2/pwm2
If you set the speed directly using sysfs you don't have the lag, this point
out that the lag occurs only when you read the speed of the fan, indeed if try
to read the speed with sysfs you still hav
Update:
The fix and the workaround together is a definite improvement, but the
lag is still present upon changing fan speed, but feels shorter, and
sometimes absent.

This workaround worked for me too.
Note that the error is still present, only sensors does not use the
erroneous function.

I reopened this problem on Bug #1405003.
This bug number #1349176 was closed on released 1.42 as I considered
that some models would benefit from the improvements I made in the code
of i8kmon. But as some models still have the lag, the problem is not
solved.

If the meaning of better is that the lag is sparser than before, I say
that it's the best where the software can reach, to the most of my
knowledge.
It is impossible to avoid the lag completely in some models as even
change fan speed is a slow call.

I've also tried the updated version and it's definitely better, but
since the lag is still present I would not consider the bug fixed.

i8kmon does not call, unnecessarily, i8k_set_fan() anymore. For sure, it
was one of the sources of the lag. But now it avoids that!
Perhaps, to somebody this bug is solved. We need some more tests here
from others models.
What is still present is querying temperature speed regularly but it
seems
I've tried the updated i8kmon, I understand the changes made, but the
lag is present at sensors query and fan speed change, so from my
perspective this bug is still present.

As the freeze exist for setting fan speed, it is impossible to remove
it.
But at least now (with the last commit) i8kmon will only call
i8k_set_fan() when it needs change fan speed. This way, freeze will be
sparser.
Please try it as a preparation for release.

i8k_set_fan does take long to run.

solazs,
I've updated the functions that are probed as it seems another function,
i8k_set_fan, also causes lag/freeze. Could you please update your local
repo, and call "./probe_i8k_calls_time" again?

In the last commit at "lp:i8kutils" I included a tool to measure the
time took by each function of i8kctl.
As the calls are the same as i8kmon's, we can identify which one is
slow, to properly correct this bug.
To compile and run, just checkout the last version, do a 'make', and
execute "./probe_
In reply to comment #8
The command "i8kfan 0 2" returns "-1 2" causes a lag for me.
Running i8kfan with any combinations of -1,0 and 0,1,2 causes the lag for me,
but simply running i8kfan does not.
This leads me to believe, that lag happens when i8kfan writes the fan speed
control file.

Same here on a Dell Insiron N7110.
issuing the sensors command also causes a lag, so I had to kill my temperature

I have the same start-stop sequence lag on a Dell Vostro 1720 with
i8kutils 1.41 on Debian.
By shutting down i8kmon (/etc/init.d/i8kmon stop) and switching to
manual i8kfan commands I can reproduce the lag/freeze for some commands,
and not for others;
cat /proc/i8k does not cause lag/freeze.

A freeze problem was solved at version 1.39. It was to be right at

But there might be another problem as just a "cat /proc/i8k" causes a

module.
