Hi Luming,

This module was build into the kernel. After make it a module and making
sure it's not loaded, I still see the problem. Here is a more detailed
problem:

If I leave ACPI to manage the system, thermal zone TZ4 stays around 80
C. The moment I turn on fan C318, this zone *shoots* up to 100 C and
stays there, no matter what. This fan I can't turn off again.

Here is a cat of fans, thermal_zone status and temp.

status:                  on
status:                  off
status:                  on
status:                  on
status:                  on
status:                  on
status:                  on
state:                   active[2]
state:                   ok
state:                   ok
state:                   ok
state:                   ok
temperature:             65 C
temperature:             61 C
temperature:             54 C
temperature:             30 C
temperature:             100 C

This was taken during the compile of gcc. While not doing anything, the
second zone drops to 54 C (currently at 61)

Thanks for the time,

Pieter

Do you have psmouse module loaded ?
(i.e. CONFIG_MOUSE_PS2=m)
If yes, Please try remove it, and re-test it.

Thanks,

Re: Fan speeds on HP nc6400 and nc8430

[emisca]

The TZ4 thermal zone on all the hp compaq line nx**** and nc**** is
not a temperature but the fan speed. You can see this information on
the web and on hp forums. I really don't know why hp has done this..
With my nx7400 I have problems with fans only when I resume from
suspend to disk and the thermal module is loaded by initramfs before
resuming the system.
I have also noticed that these laptops consume more energy on linux
than on windows.
I think that's a problem related to acpi C states. On AC I have only
C1 and C2 on both cpu cores, on battery I have C1, C2 on first core
and C1, C2, C3 on the second. Why there are no higher C-states?

Show:
cat /proc/acpi/thermal_zone/TZ0/trip_points

or change TZ0 to TZ1

For many HP notebooks first trip point is to low. To change manually,
for example:

echo "105:100:100:78:70:60:50" > /proc/acpi/thermal_zone/TZ0/trip_points
echo 10  > /proc/acpi/thermal_zone/TZ0/polling_frequency

Then I have:
maciek@rutek:~$ cat /proc/acpi/thermal_zone/TZ0/trip_points
critical (S5):           105 C
active[0]:               78 C: devices=0xcf7aea40

active[3]:               50 C: devices=0xcf7ae93c

maciek@rutek:~$ cat /proc/acpi/thermal_zone/TZ0/polling_frequency

Someone also sent me this, which I'll include in case it helps anybody
else.  Obviously, scripts like the one mentioned below are stop-gaps
that shouldn't be necessary.  But the script might have useful hints
about how to fix the kernel so the script would no longer be needed.

Re: Fan speeds on HP nc6400 and nc8430

[emisca]

I was wrong on that post....
I've found that the initramfs scripts loaded thermal module before
resume from suspend to disk (this is the default behaviuor of debian
based distros). That confused the bios...
That was the only problem.

Hi Guys,

I tried the suggestion below and it didn't seem to change anything - I
even set the same trip points to TZ1. The fans still seem to spin faster
in Linux compared to Windows. Then the other issue is that I can't
switch a fan off once I force it on.

Thanks,

Pieter


Show:
cat /proc/acpi/thermal_zone/TZ0/trip_points

or change TZ0 to TZ1

For many HP notebooks first trip point is to low. To change manually,
for example:

echo "105:100:100:78:70:60:50" > /proc/acpi/thermal_zone/TZ0/trip_points
echo 10  > /proc/acpi/thermal_zone/TZ0/polling_frequency

Then I have:
maciek@rutek:~$ cat /proc/acpi/thermal_zone/TZ0/trip_points
critical (S5):           105 C
active[0]:               78 C: devices=0xcf7aea40

Re: Fan speeds on HP nc6400 and nc8430

[emisca]

I have noticed that disabling cpu frequency scaling doesn't matter too
much on my core 2 duo processor. On normal usage the temperature is
50° with fixed 1.66mhz and tz4=30 (fan speed), and 45° using
cpufreq-ondemand (tz4=30). This is not a big difference...

I have a patch that should fix the psmouse unload thing (at the end).
Not sure whether it's still needed in 2.6.20-rcX, there was some work
done... it definitely helps on 2.6.18 and 2.6.16 kernels.
Ok, I quickly tried on 2.6.20-rc7 and it seems to work without the
patch.
Maybe Dmitry can comment on that and push this one if still needed?

It's quite difficult to get the overview over the HP problems, as there
are several, some quite weird, and a lot different reports.

I've found out that the psmouse thing really fixes things.

and I got a lot reports that Alexeys patch (and the
unregister_serio_drivers attached) fixes up things:
https://bugzilla.novell.com/show_bug.cgi?id=179702
https://bugzilla.novell.com/show_bug.cgi?id=234475
As this patch broke Linus' machine, I understand that Len is a bit
anxious, but a lot people tested the reworked patch (it's currently in
10.2 and SLE10-SP1 SuSE branches), it would be great if Len can push it
at least for the next kernel cycle...

What is still broken, but patches are available, is fan state after
suspend/resume.

Thanks to Rafael, there is a list of patches that seem to help
(including Alexey's and some others) here:
http://www.sisk.pl/kernel/patches/2.6.20-rc5/

Most of them seem to come from:
http://bugzilla.kernel.org/show_bug.cgi?id=5534
and
http://bugzilla.kernel.org/show_bug.cgi?id=7122

Can someone give an overview about what is already submitted, what is
going to be merged and where/when (-mm, rcX, 2.6.21-rc1, ...).
All kind of comments/review/tests are very welcome...

Some of the patches miss a comment...

Thanks,

Subject: Unregister serio drivers on shutdown
From: Thomas Renninger <trenn@suse.de>


Unproved theory:
It seems that the Embedded Controller needs this at ACPI shutdown time:
    psmouse_set_state(psmouse, PSMOUSE_CMD_MODE);
    psmouse_set_state(psmouse, PSMOUSE_IGNORE);
done in psmouse_disconnect in psmouse module.

If this is not done on shutdown it leads to very strange BIOS/EC behaviour
on latest HP laptops which even survives a reboot (cpufreq cannot reach max
freq, BIOS takes long to boot, etc.). Then the fixed kernel needs to
be booted twice, that machine reaches max freq and behaves normal again.

I do not like the idea of removing port at shutdown. I will look into
extending psmouse_cleanup so it leaves the port in the same state as
psmouse_disconnect.

I managed to get a HP NX 6330 laptop to test HP laptop related issues
discussed here.
But the bug http://bugzilla.kernel.org/show_bug.cgi?id=7813 seems to
be NOT reproducible on my NX6330. This fact prompt if there are any
essential difference between NX6330 and NC6400. The BIOS of my NX6330
even declares itself is NC6330.

I'm not clear on HP's numbering scheme. It doesn't make any obvious
sense to me!

Mine is a nc6320 which exhibits the above bug. The DSDT lists as nc6340
though. That is an Intel Core Duo, with the following lspci output:

Hi,

Could you please try the 2 attached patches and let me know if it improves
suspend and psmouse iteractions.

Thanks!

Some people report that they need psmouse module unloaded
for suspend to ram/disk to work properly. Let's make port
cleanup behave the same way as driver unload.

On my box (nx6325) it does.  Apparenly, with these two patches applied I don't
need to unload psmouse before the suspend so that the power management works
after the resume. :-)

I'll be testing it a bit more today anyway.

At what kernel are targeted these patches? I have an nx7400, and the
same psmouse problems.... I would like to test them..

Please try 2.6.21-rc2 - the patches are included there.

Do you have psmouse module loaded ?
(i.e. CONFIG_MOUSE_PS2=m)
If yes, Please try remove it, and re-test it.

Thanks,

Fan speeds on HP nc6400 and nc8430

Hello List,
 
I have noted that the fan speed on "idle" is much higher in Linux
compared to XP. I have also noted that once fans are turned on, they
never seem to return to the off state. I am currently using the 2.6.18
kernel from Gentoo (gentoo-sources-r6). I was wondering if there is a
way I can lower the fan speed, or even assist the devs to get info
regarding these notebooks (if any is needed).
 
Thanks,
 
Pieter
