[2.6.33-rc2] ACPI problems on HP nc6400 notebook

[2.6.33-rc2] ACPI problems on HP nc6400 notebook

[Sedat Dilek]

Hi,

I build linux-2.6.33-rc2 on a Debian/sid 32-bit host.
Unfortunately, this kernel falls in an unusable state (sort of loop)
and does not a normal startup.

With this setting (see below), I hoped to catch the early
boot-messages (but, no success):

# cat /etc/default/bootlogd
# Run bootlogd at startup ?
BOOTLOGD_ENABLE=Yes

Finally, I could take a picture [1].
It seems to be that latest ACPI patches are breaking my system (speculating).

Q: How can I log such early boot (error) messages to give a detailled log?

Hope this helps fixing the problem.

Kind Regards,
- Sedat -

you can try(if you have the port)
ohci1394_dma=early or the usb
early logging located in kernel hacking.

but if this thing is hitting way early it
might be a bit more tricky.

if you can try  a bisect from the bad
kernel to the good.

Hi,

as I suspected it is an ACPI issue while I tried to boot with "acpi=off".

I have taken new screenshots and added dmesg (acpi=off) and all
messages in /var/log/* [1].

It is possible to load acpi kernel-module afterwards?
Or it is not possible whenn loading with acpi=off?

@Len Brown:
There are two photos showing thermal problems.
Notebook did shut down in the night.
But this was before 2.6.33-rc2.

I will not try a bisect (visting currently my brother and working with
touchpad really sucks), but I will revert the wmi-related (wmi/hp-wmi)
commits.
There seems problems with wmi on other systems w/ 2.6.33-rc2 [2].

Kind Regards,

...and now I could boot into 2.6.33-rc2.

Re: [2.6.33-rc2] ACPI problems on HP nc6400 notebook

[Sedat Dilek]

[-- Attachment #1: Type: text/plain, Size: 5249 bytes --]

While dell-wmi and hp-wmi is concerned I only applied this patch (see
file attachment):

    0001-Revert-wmi-Free-the-allocated-acpi-objects-through-w.patch

This fixes ACPI/WMI problems onmy HP nc6400 notebook.

----- Please REVERT the following commit in 2.6.33-rc2 -----

    wmi: Free the allocated acpi objects through wmi_get_event_data

    These function allocate an acpi object by calling wmi_get_event_data, which
    then calls acpi_evaluate_object, and it is not freed afterwards.

    And kernel doc is fixed for parameters of wmi_get_event_data.
