dmesg from kernel

Dmesg from the latest development kernel with CONFIG_ACPI_DEBUG enabled

Downstream report: http://bugs.gentoo.org/show_bug.cgi?id=105570

Do you have any problems with ac/battery state, I mean wrong system behaviour 
or something else, or you have wrong "battery absent" line in dmesg messages 
only?

What is the content of /proc/acpi/ac_adapter and /proc/acpi/battery files if 
you have "battery absent" message?

Well, my battery note being seen implies; /proc/acpi/battery/BAT1/state saying:
present: no.
Most battery monitoring programs use this, meaning I don't know how empty my
battery is, and this makes it a problem. When I don't have my AC plugged in, I
would like to know the amount of power I have left, so I can shutdown correctly etc.

Nice timing :)
Here is what you wanted to know:

1 - When booted with ac unplugged:
s050414 ~ # cat /proc/acpi/ac_adapter/ACAD/state
state:                   off-line
s050414 ~ # cat /proc/acpi/battery/BAT1/*
present:                 no
present:                 no
present:                 no

1.1 - When I then plug in AC:
s050414 ~ # cat /proc/acpi/ac_adapter/ACAD/state 
state:                   on-line
s050414 ~ # cat /proc/acpi/battery/BAT1/*

2 - When booted with ac plugged in:
s050414 ~ # cat /proc/acpi/ac_adapter/ACAD/state 
state:                   on-line

Yes, this is a real problem.
What kernel version do you use?
Do you have any info on other kernels?
Please attach 'acpidump' output for the wrong state.

I have this problem now with the 2.6.15-suspend2-r8 kernel (gentoo patches and
suspend2 patch), and with the vanilla kernel 2.6.16-r5 (the attached dmesg is
from that kernel). Had this problem before with an older kernel with gentoo
patches (it was 2.6.12 kernel).

How can I get an acpidump (Can't find a package called acpidump, and it's not
already installed on my system) ?

acpidump output

Found acpidump (Thanks Daniel).

Please try build kernel with preempt off, and re-test.

Tryed it, changed CONFIG_PREEMPT to n, and recompiled, rebooted. Didn't change
anything. Tryed it for both the development kernel, as the suspend2-sources
(gentoo patches and suspend2 paches).

I have the same problem with 2.6.16 kernel version.

At boot sometimes i get the following errors:

When it happens my laptop is unable to read battery remaining capacity level

Jeroen,

Please install and boot the latest stable kernel 2.6.16.1.
Check that problem persists.
Apply the battery patch.
Install and reboot the patched kernel.
Post the dmesg output, content of /proc/acpi/battery & /proc/acpi/ac_adapter
files and /var/log/acpid.
It will help us to understand and fix the problem.

Maurizio.

This is other problem. Please create the new bug.

> When it happens my laptop is unable to read battery remaining capacity level

Please describe it.

At the moment I don't have my laptop, it is being fixed. It looks like the
battery fails to load, so it might simply have been that. I expect it back in a
week, and will let you know then.

No response from bug submitter, please reopen if problem persists.
