Summary: Fan of my HP NW9440 spinns full speed when it is idle.
This laptop uses acpi-fan.
Product: ACPI
Version: 2.5
Kernel Version: 3.6.5
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Fan
AssignedTo: acpi_power-...@kernel-bugs.osdl.org
ReportedBy: morpheusxyz...@yahoo.de
Regression: Yes
The fan of my laptop spinns full speed after a while when it is not under any
load. To reproduce this the following conditions have to be met:
1. let the laptop enter the lowest fan speed. This is fan off when running on
battery or the lowest speed when running on ac.
2. Do nothing on the laptop. Just let it sit there. After a while the fan
starts spinning full speed. This is not always the case. Sometimes the laptop
works for days before I get this bug again. Perhaps it is important to know
that the laptop even under heavy load does not engage full fan speed. The last
but one speed is sufficient to cool this machine.
The laptop is a HP Compaq NW9440 EY612EA#ABD. It has a nvidia quadro fx1500m
graphics chip. Problem is that the system shares one cooling system for cpu and
graphics card. I can only observe this bug when the nvidia binary blob is
enabled because no other driver lets the system reach the lowest possible fan
speed. With the nouveau driver the fan speed is two steps faster when ideling.
The latest kernel version without this bug is 2.6.31. After this kernel all
kernels have the bug under the same conditions. Latest tested version is 3.6.5.
I have tried to bisect this but ran into a dead end because sometimes the
nvidia driver would not work and other times the bisected kernel crashed my
computer. Because this problem is so annoying I kindly ask you to give me a
hint where to look to get rid of this problem.
Furthermore I did this 'echo disable > /sys/class/thermal/thermal_zone0/mode'
for each thermal zone. But it did not help. Neither did the playing with the
acpi_osi parameter nor fixing the two bugs of the DSDT table.
Output of acpi -V:

Interesting thing is when the bug occurs there is no active thermal zone or fan
visible in acpi -V.
I tried to get help from HP for this but they said I should use Windows!? I
know my kernel is tainted but I hope to get some hints as to where I can look
and what I can try to get rid of this bug. I even tried to replace all of the
acpi drivers with the old ones. But since I am no programmer it failed to
compile. Any help is greatly appreciated.
