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

Subject: psmouse - properly reset mouse on shutdown/suspend
Input: psmouse - properly reset mouse on shutdown/suspend
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.

Re: Fan speeds on HP nc6400 and nc8430
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 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 <[EMAIL PROTECTED]>
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.

Re: Fan speeds on HP nc6400 and nc8430
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. 2007/1/24, Bjorn Helgaas <[EMAIL PROTECTED]>: On Tuesday 23 January 2007 21:38, Bjorn Helgaas wrote: > On Tuesday 23 January 2007 21:19, Luming Yu wrote: > > On 1/19/07, emisca <[EMAIL PROTECTED]> wrote: > > > The TZ4 thermal zone on all the hp compaq line nx and nc is > > > not a temperature but the fan speed.

Re: Fan speeds on HP nc6400 and nc8430
From the thread, I see Emilio Scalise has resolved the problem by hacking DSDT. So it would be helpful to verify. (Please check this thread http://www.mail-archive.com/linux-acpi@vger.kernel.org/msg02785.html) I don't have this laptop, so I don't know if it really work. But, I will check how it was resovled. Probably, we can find out the root cause. But I'm still confused by the fact that Windows just works. http://www.mail-archive.com/linux-acpi@vger.kernel.org/msg02785.html On 1/24/07, Bjorn Helgaas <[EMAIL PROTECTED]> wrote: On Tuesday 23 January 2007 21:19, Luming Yu wrote: > On 1/19/07, emisca <[EMAIL PROTECTED]> wrote: > > The TZ4 thermal zone on all the hp compaq line nx and nc is > > not a temperature but the fan speed.

Re: Fan speeds on HP nc6400 and nc8430
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?

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.
