Bug Description

On my notebook acer aspire 5930G on upgrade to 10.04 version, after few minutes of use apci stops working (don't recognize ac/dc or battery, don't change lcd blacklight, etc.) and start to flood dmes with this messages:
[ 767.208058] ACPI: EC: input buffer is not empty, aborting transaction
[ 767.208072] ACPI Exception: AE_TIME, Returned by Handler for [EmbeddedControl] (20090903/evregion-424)

Trying to reboot (or to shutdown and restart) my pc don't want to boot!

WORKAROUND: Get out the battery and replace.

Hi Luca,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

That issue re-appear after i ibernated and waked up hours after my notebook.
I rebooted (by removing the battery :( ) and no other issue appear in last day, where I turned off and suspended the notebook several times.

Could it be a problem of hibernation at this point?

No, it could be a problem with acpi monitor!! In the sense it disappears after i removed "Hardware Sensors Monitor" from my panel.

Please ask me if you need more (detailed) information.

Must be the worst ubuntu bug i ever experienced. When it first occurred, i thought it was some kind of hardware failure, so i tried another kernel (rt) and it went fine until i replaced it with the main kernel again, and it *does* break everything exactly like described on the first bug report.
Btw, why is this HUGE bug marked as "incomplete"?

Thanks!

The kernel mentioned in message #17 unfortunately does not solve the problem here.

I've got the same laptop model as the OP, but running Archlinux. I though I could shed some light on this issue.

There's an open kernel bug for this: https://bugzilla.kernel.org/show_bug.cgi?id=14733

It affects all the kernel since 2.6.32, the only way to have a functional system is applying the "Add delay before data write, take #2" patch to the kernel source.

I'm writing this here since 2.6.34.1 is still affected by this bug and there seems to be no activity on the kernel bugzilla, maybe Ubuntu can push things a bit. It's quite a important problem as it does inhibit the possibility to turn on the PC (when shutting down, remove AC and battery and replug them in).

I've tested 2.6.32.6 and 2.6.34.1, the only way to have them running correctly without 1s delays every 5 seconds and ACPI errors in the kernel log is to apply the patch.

So, i compile kernel 2.6.32 get from ubuntu repository following this two guide:
- http://forum.ubuntu-it.org/index.php?topic=368450.0 (italian)
- http://ubuntuforums.org/showthread.php?t=56835 + sudo update-initramfs -c -k <kernel version> + sudo update-grub (english)
They are equivalent, more or less.

Before compile i applied this two patch:
- http://launchpadlibrarian.net/37672643/patch from https://bugs.launchpad.net/ubuntu/+source/linux/+bug/505420 (otherwise compiling exit with error)
- https://bugzilla.kernel.org/attachment.cgi?id=25261 , suggested by Stèphane

Now i stress my system and i'll report you result.

After 7days of testing, i'm so happy to annuce that with the previus passages the bug has disappeared!!!oleeeee!

Thanks Stèphane!!

I agree. I have been running a kernel I complied myself with the patch
listed above to ec.c....since then, the computer has been been going
into and recovering from stand by with no problems...I have not had to
pull my battery once to reboot! Hopefully this patch will be
incorporated into a future kernel release...I do hate being stuck on a
patched kernel!

hi, i have the same problem with Maverick 10.10 with kernel 2.6.35.22, i tried to update the kernel to 2.6.36 but the problem persist, i also updated the bios and here the pc changed his behavior before it will hung at the screen boot (with the acer logo) now it try to load the system but at 1/3 ot the loading bar of the bios it crash and it try infinitely to load it again until i pull my battery and the ac/dc..
i noticed that before the errors appear i have always these two strings:
lo: Disabled Privacy Extensions
CE: hpet increased min_delta_ns to 11250 nsec

i don't know if they are related to the problem.

the patch listed above can i apply to the current kernel version?
(excuse me for my english -i'm italian- and i hope you'll solve this problem soon because i don't want to leave ubuntu)

hi Arathon

you must not leave Ubutnu, all the other linux based OS have the same problem. It's the kernel.
I use gentoo and have it too.

I will also try to patch the Kernel and hope it will finaly solve this annoying problem.

Hi ArathoN,
yes i hope you can apply that patch to all 2.6.x kernel.
Just yersterday i've patched (and recompiled) kernel 2.6.35.4 of ubuntu maverik.

i hope it will work because ubuntu is a good distro and i'm liking it.

@Zenatti: ma sei riuscito ad applicare normalmente la patch a me da un po di errori (hunk ...), ma poi devo recompilare per ogni aggiornamento del kernel (patch) che faccio?

Si sono riuscito, ti sposti nella cartella dei sorgenti che vuoi
patchare (/usr/src/linux-....), ti copi le due patch che ho segnalato
sul launchpad, prima applichi
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/505420 e poi
https://bugzilla.kernel.org/attachment.cgi?id=25261. per applicare le
patch dai patch -p1 --dry-run < filepatch , in questo modo "testi" la
patch, se non ricevi errori ridai il comando senza --dry-run. poi segui
le guide per la compilazione e non ti dovrebbe dare errori.
Naturalmente ricorda di fare tutte queste operazioni con il sudo.

For apply patch you have to digit "patch -p1 < /pathto/patchfile" into linux source directory. If you want simulate patch, add --dry-run option at patch command.
I suggest you to apply patchs in this order:
- http://launchpadlibrarian.net/37672643/patch from https://bugs.launchpad.net/ubuntu/+source/linux/+bug/505420 (otherwise compiling exit with error)
- https://bugzilla.kernel.org/attachment.cgi?id=25261 ec patch ;)

After that you can go on to compile your kernel. You have to do it every time you change kernel, until ubuntu or kernel team not resolves that issue.

ArathoN (turionavanon) wrote :

i tried to apply the patches you told in the previous post but it gave me some error with them so i modified the file ec.cc adding and removing the necessary lines and compiled with Kernelcheck, that it gave me an error during the installation because it couldn't configure the nvidia module, but i resolved reinstalling the compiled kernel manually, now i'm testin if the patch is working, and i must tell that the system is more stable and until now no errors reported in kernel.log, i'll test for another 3 days than i'll report if it's working or not.

i noticed that the lines in the patch are different from the line in the original file (ec.cc) (considering the ones that are present in both infact the number of the lines differ), i think taht it's 'cause of this that patching gave me these errors, so please fix the patch some someone else noob like me wouldn't spend days trying to patch their kernel.

i'm also surprised that this patch wasn't applied directly to the current kernel of maverick and after because is a very serious and annoying problem, infact:
1-it didn't recognize my battery (always at 95%)
2- the hardware temperature was also a mess (cpu: -1 °C) so more possibility to damage your hw
3-the system hungs a lot (also the mouse if you press ctrl or shift)
4-impossibility to see hd video, the system can take the load to encode it (now is playing them great)
5-then the system at some point doesn't respond at any commend and you must unplug it from battery and ac/dc
so i hope that you will apply definitely this patch.

Well, i have to apologise for not coming back here to show my results, particularly with Ivasyuk, who gave me the kernel advice; and bpowell, who expected to see my results, as we have the same model. Sorry guys :/

The thing is, i'm still using 10.04 with the "rt" kernel, i tried several packaged kernels from that ppa mentioned earlier, and the problem doesn't seem to be solved yet. I'm running out of time these days, so i don't expect to be applying patches soon, and when i do, i will try to post my results here (seriously).

And i do hope the kernel team could solve the things up, there's something really wrong with latest kernels, and i mean *really* wrong, because i experienced weird bugs (unrelated to this one) trying to help a friend to install "the meerkat" on his desktop.

ArathoN (turionavanon) wrote :

i noticed that with the latest kernel version of the kernel for maverick the problem is half solved, now if i have the notebook plugged only with ac/dc , there will be no errors regarding the acpi , the same things happen with only battery, but if i plug the battery with ac/dc and if the battery has finished charging the error appear telling that it didin't find any battery, slowind down the system, in fact if the battery is charging there will be no errors. If you want more information ask.

so a work around is to use rt kernels instead of pae? we can miss 1gb of ram but have an ac/dc detection corret and no need to pull of the battery every starting?

( Thanks Luca ! )

but with

a) using 3.5.7 as the kernel version
b) this patch https://bugzilla.kernel.org/attachment.cgi?id=25261
c) not adding vesafb and fbcon to /etc/initramfs-tools/modules

The message:

and things seems to be stable so far.

Hi all,

I'm on Acer 4741 laptop. I multiboot and I've problem with all the distro I have on this computer (e.g. Slackware 3.2.29 kernel, Ubuntu 3.2.0-29-generic-pae kernel). This has been like this for about 2yrs already.

I applied the patch given above with minor adjustment to one of the function name (from ACPI_EC_DELAY to ec_delay) and it seems to work fine as of this post. Now, I'm stuck with this 'patch' work until this is included in the main kernel, which seems to be bleak given the fact that this issue is atleast 2yrs old already.

My question now is how and from where do we get this patch for every kernel release? Luca, you have been posting diffs for several kernels. How do you do that?

Thanks, SV

I'm also affected by this bug since ubuntu 10.04.. It's getting very annoying.. I have a Acer Aspire 5930g laptop, 3.5.0-21-generic kernel, ubuntu 12.10.
Thing frustrating part is that after i get this message usually the computer won't pass the post screen, just like in this clip: http://www.youtube.com/watch?v=rndKUE_CzLs

Is there a solution to this?? I can't take it anymore!

ACPI: EC: input buffer is not empty, aborting transaction
ACPI Exception: AE_TIME, Returned by Handler for [EmbeddedControl] (20120320/evregion-501)

 A solution to the computer not passing the Post screen is to disconnect the pc from the electric power and to remove the battery for a few seconds. After reinserting the power and/or the battery my acer 5930G passes the post screen and boots.

I do not remember if this has already been written in one of the posts above and, if not, where I learned that.

Best regards, gabriele

Hi all,
I have experienced the same problem on my aspire 5930G...reading some posts, it seems to be a very common problem with linux and this laptop.
For me it's not so annoying, as I encounter it few times, but I know there are some problems. For example, my battery seems to be recognized and charged well, but the estimation of the left charge and other parameters are wrong.
I have now Ubuntu 12.10...I was trying to understand by myself if there's a way to solve this issue. I read about a patch in the first posts...is it still a valid solution? Or maybe there have been some improvements?
Thanks in advance

I have an acer aspire 5930G. Maybe there's something with the laptop's BIOS... I could not find an update since v. 1.24 from 2008.
I've read in this thread about patching, but I didn't quite understand how to do it..
Hope to fix this as soon as possible!

How do I apply the patch for my 3.5.0-21-generic kernel...?
I am beginner and didn't quite understand it... Could you please explain again?

LuisIbanez says that he patched his kernel, which was version 3.5.7...can the same procedure be applied to the latest kernel?
Sorry for annoying you, but I've never done it before and I need my laptop fully working.

Hi,
the procedure is almost the same for all kernels, it can changes on rows of
ec.c that must be patched. But it is simply to adapt to different version.

Just unzip it...it'll have the two .deb files you need to install a kernel...then you'll just need to use the package manager of your choice to install it.

Grecu: Sorry to hear that. Works fine for me on 12.04 LTS...ACER 5735.

I can confirm this bug for my Samsung R60 Plus, running Debian, with every Kernel I tried from Squeeze trough Wheezy (2.6.32 - 3.2.0) and several Liquorix Kernel releases (latest was 3.8). When the bug hits, input of any kind is no longer possible. Music or videos currently running are continuing to do so. Unplugging the laptop from the power source won't make a difference (as in, the backlight brightness won't reduce as it usually does) - it just seems to continue running as it would be while stilling being connected.

In the past I was running the Xfce4-Power-Manager. Whenever one of those freezes happened I just pushed the power switch on my notebook and the system de-froze. In the configuration the result of activating the power switch was set to "Fragen" (ask me). Running i3 a temporary fix for me would be to autostart the Xfce-Power-Manager and "de-freeze" the system manually once it happens (which is, as of now, roughly once every day).

But waiting for the problem to fix itself won't do, it seems. I guess I'll have do dive into Kernel patching and compiling in the long run - one thing I hoped I don't have to do, ever.

Guys, this bug has had its patch submitted upstream to the kernel developers (https://bugzilla.kernel.org/show_bug.cgi?id=14733), and as of Monday, is with the ACPI mailing list (https://patchwork.kernel.org/patch/2521951/).
So progress is happening, slowly but surely.

So, I also have the same problem since one year more or less. Same problems as everybody on my Acer Aspire 5730z (the problems has been occurring with both 32bit and 64bit operating systems):
1) infinite lines of this kind:

2) when the laptop does not reboot, I unplug the mains power and also the battery and then push the bower button for a couple of time, then plug the battery and/or the cable or both and everything works on again.

3) problems sometimes when trying to tune the LCD brightness, the system can even hang definitively and halting/rebooting is the only "solution"

4) generally, the system suffers some slow downs

5) one of the 4 usb ports is not working (is it related to the original problem?)

6) I'm not sure whether 64bit Linux based operating systems (as well as Win XP Professional 64) fully recognize the 4GB of RAM (is it related to the original problem?)

Dear Joseph,
thanks for your suggestion.

How could I check how much RAM is reserved to my graphic chipset by the
BIOS / OS?
According to what BIOS says, only 64MB are reserved to graphic card.

Any suggestion, please?
Thanks.

Any suggestion on how to check the detailed RAM consumption/reservation by both kernel and BIOS?
Thanks,

The same problem still occurs, and more frequently than with the 3.2 kernel series it seems.

Works perfectly without any patching. Now I'm not getting error about "input buffer is not empty..".
Also, all ACPI works well (lcd backlight control, battery state, etc.)

description: updated

I have had this problems for years.
On my Acer 5930G this problem has disappeared one month ago, once I updated to Linux Mint 16 and to kernel 3.11.
Should this bug be marked as ''solved''?

Best regards, Gabriele Bianchi

Luca Zenatti, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc3

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.
