ACER 3201cxi Laptop hangs when loading ac module

wThanks for taking the time to report this bug. Unfortunately, we are not able
to fix and find the bug because your description of the bug didn't have enough
information in it. We suggest you read `How to report bugs effectively', [WWW]
http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you
would then add more useful information to this bug.

This issue was first raised by me at http://ubuntuforums.org/showthread.php?t=68630

Also tried to follow the instructions on this link at least 4 times without
success:
https://wiki.ubuntu.com/ACPIBattery

In essence this is the problem:
The latest kernel I have installed is 2.6.12-9-386, which apparently has built
in ACPI support. But when I try to boot using this kernel the boot process stops
when it attempts to load the ACPI modules. I suspect that if I add the boot
parameters noapic and nolapic I suspect it will boot.

I have reverted to kernel 2.6.10-5-386 for the time being.

Booting with kernel 2.6.12-9-386 hangs the machine when loading the ACPI modules.

Installed kernel 2.6.12-9-386, went through the duffman25's APCIBattery page
https://wiki.ubuntu.com/ACPIBattery and did the Breezy update (at the foot of
the page).

Rebooted - hung on loading APCI modules (or something like that - can't
remember), so I tried to add the two boot parameters that duffman25 suggests (I
did one at a time, then both), and this made no difference.

Reverted back to kernel 2.6.10-5-386, no further forward.

We need the exact error message that you see before it hangs.

When booting (kernel 2.6.12-9-386) there is no error message as such.

On the graphical splash screen I get: 'Loading ACPI modules'

Then the screen switches to text mode and I get: 'Loading ACPI modules ...
         y ... [ok]'

And then the computer hangs at this point.

Please boot the system in recovery mode, then run:

for file in /lib/modules/`uname -r`/kernel/drivers/acpi/*.ko; do
  modname=$(basename $file .ko)
  echo "Trying to load: $modname"
  modprobe $modname
done

and copy the output here.

I ran the script as you suggested. The output is as follows:

Trying to load: ac

At this point the machine appears to hang and I had to restart it (using the
previous kernel).

OK, in this case you should be able to reproduce the hang by booting into
recovery mode and running "modprobe ac". At that point, press alt+sysrq+t to
get a trace, and send it to us (a digital photo is usually the easiest way to
capture it)

I have just added 'acpi=off' as a boot parameter (kernel 2.6.12-9-386) and the
machine now boots. Now power management of course.

Sorry, that should say NO power management

Just discovered, using kernel 2.6.12-9-386, that not only can I not get power
management or battery monitoring working, but also that my synaptics touchpad
doesn't work and the wireless network also doesn't work.

I have reverted back to kernel 2.6.10-0-386 and although my wireless network
works, I still have no power management, battery monitoring, or synaptics touchpad.

Not sure if these are related, to my original power management issue, but I
thought I would report these issues anyway.

Ian

Ooops - should be reverted back to kernel 2.6.10-5-386

I have made a little progress:

See http://ubuntuforums.org/showthread.php?t=75814

Hello

Is there any progress with this issue.

The only thing I cannot get to work is the ACPI for power management.

Regards

Ian

My laptop does not display battery status either.

Acer Travelmate 4000

If possible, please upgrade to Dapper's 2.6.15-7 kernel. If you do not want to
upgrade to Dapper, then you can also wait for the Dapper Flight 2 CD's, which
are due out within the next few days.

Let me know if this bug still exists with this kernel.

Hello

I am now using Dapper Drake,running kernel 2.6.15-8-386.

The ACPI modules still do not work.

I can't find a DSDT for my laptop (system bios 3A08).

There is no power management or battery monitoring.

Hope this helps.

Can you elaborate on "do not work"? Does it still hang, or is it just not
working correctly?

Created an attachment (id=5508)
Output of dmesg

My laptop starts OK without having to add 'acpi=off' or 'noapci' parameters in
/etc/grub/menu.lst.

However, I think the ACPI modules load OK - see the outbut of dmesg in the
attached file dmesg.txt.

When I run the power management application, or add the Battery Charge Monitor
to a panel in Gnome, I get no battery present and 0% charge, regardless of
whether the battery is running on mains power or battery.

Therefore I cannot see how much battery is remaining (if I use the laptop on
battery only, it suddenly shuts down without warning when the battery runs out).

The hibernate and suspend features are also not enabled.

Hope this helps.

Can you attach the output of these two commands:

find /proc/acpi/battery

cat /sys/power/state

Thanks

Ok, then not much we can do there. Attach output of "sudo dmidecode" and let's
see what's there.

How are you trying to suspend? Shows that you support suspend-to-mem and
suspend-to-disk. What happens when you attempt to suspend?

Created an attachment (id=5512)
Output from 'sudo dmidecode.txt'

I do System->Logout->Suspend the computer to suspend it.

It fails in that I have to switch the laptop off completely (holding the power
button in for 10 seconds) as I can't recover from the suspend, and completelt
restart it again from scratch.

Hibertaion (System->Logout->Hibernate the computer) partially works. After
hibernation, when I (momentarily) press the laptop's power button, the system is
restored to it's previous state. Except it is sluggish, particulary with my
logitec usb mouse. It becomes almost unworkable.

The laptop's hotkey for suspend/hibernate does not work either.

The output from 'sudo dmidecode' is in the attached file dmidecode.txt

I have also noticed that during boot the following error occurs:

'Setting sensor limits => fail'

Not sure if this has anything to do with the problem, but I'd thought I'd
mention it.

Ian

I am now using Dapper Drake,running kernel 2.6.15-11-386

The situation remains the same.

I have an acer laptop as well (4101WLMi)
And power management/battery levels does not work either.
I have to boot with nolapic
I believe the battery problem comes from acer using 'smart batteries'

I was successful in fixing and recompling the dsdt and creating a new initrd,
after that I was able to view my battery status.
Just thought I would drop a note in case it can help anyone, or help fix the
problem.

(In reply to comment #28)

Hi, I have an Acer 1652WLMi, with Breezy working. I too cannot get the Battery
Status working. This means that neither the Battstat applet works (it alway give
the plug icon, even when laptop is unplugged, and says Battery level i 0%), and
also that any other program trying to get Battery info does not work (for
eample, I have configured Gkrell to do this, and it says "no data" under the
IBAM section, and Battery 0%). I also cannot get any sensor working for the fan
(though the THRM sensor works properly, even if fan starts at random levels, it
seems). I can boot with the sole "noapic" settings.
Looking around in forums it seems that the Battery problem is due to the DSDT. I
heard someone made it by following the ACPIBattery Howto on Twiki.
The Saugeforce seems to have no DSDT for my model.

Can anyone tell me if there is a step-by-step way of creating a new DSDT and
what one should do more? (sorry for the step-by-step, but I'm a real newbie...)

I think the battery and fan issue are related. Originally the Processor Freqency
Scaling was not working too, but I could manage to fix it and now i works.

Thanks for any help...

Reducing priority since this appears to be a hardware issue.

Is it fine with feisty ?!
