View Full Version : [all variants] Daru2 and Latest Update

Hello,

I've just updated my Ubuntu 8.10 installation on the Daru2 I own and found that the ACPI is broken...

I'm always booting the Daru2 with the kernel option "acpi=noirq".

After the update I rebooted, and after a few minutes my Battery was lost (even running in command line showed it's lost).

I thought, let's try booting w/o the "acpi=noirq" option but that too, after a few minutes it was lost.

I also noticed, that when the ACPI gets crazy, the ACPI sensor shows the CPU is at 146 degrees Celsius (just thought I should mention that).

Does anyone else have the same problem ?

Where can I find the logs about the EC thingy or anything that relates to this old old problem (not to mention my ancient suspend thread).

Thanks,
Idan.

First, if that CPU temp is correct, it is VERY hot. I'm not sure that it is accurate. But you should make sure you don't have a dust bunny living in your cpu fan or something. Also make sure you're not obstructing the vents when you use it.

Second, are you running proposed updates? Go to System > Admin > Software Sources to find out. If so, you probably should not. You should probably disable them and go back to the previous kernel until the kernel is officially released.

After you check out #1 and #2, please post the output of...


uname -r

I can attest to ACPI thermal problems. I am sure it is not the real CPU temperature (146 Celsius), since the laptop itself it is not getting hot at all.

As a temporary fix, I am booting to an older Kernel (I think it is .9.xxx instead of .11.xxx version).

Hi Tom,


When ACPI is crazy the temp states by default 146 Celsius. When it works, the temp is correct. Now it works and my temp is 52 Celsius.
I'm not using proposed.
The output of 'uname -r' is: 2.6.27-11-generic


I've just rebooted, and uptime is about 26 minutes - ACPI didn't go crazy yet.

OK, then it probably isn't accurate.


2. I'm not using proposed.

See what happens in the *-9 kernel (per gaussian)


3. The output of 'uname -r' is: 2.6.27-11-generic

There's a bug report already at launchpad.net/system76 on the DarU2 power management problems. Please add this info to that bug, and I'll start to figure out what's changed in the kernel options.

This appears to be the relevant bug report at kernel.org. They don't seem to be using acpi=noirq but the symptoms are very similar and are all MSI machines.

http://bugzilla.kernel.org/show_bug.cgi?id=12011

BTW, the acpi=noirq fix works in 2.6.27-9

*Wild guess* that this is the patch that caused the regression:

I'm on 2.6.28-1 in Archlinux & the acpi=noirq option seems to be doing something again.
It disables the Fn-F4 & Fn-F5 keys, it had stopped doing that in previous releases.
I looked at the ec.c code & a lot has changed since the msg01302 patch.

The power readout hasn't glitched yet, but I won't feel real good about it
until I see it go many more hours with no problems :rolleyes:

i had the same problems, just with my self compiled kernel wich works only in acpi poll mode.
but i made some good experience with some changes mentioned in this bug report http://bugzilla.kernel.org/process_bug.cgi
I changed ACPI_EC_UDELAY from 100 to 500 and add some udelay(ACPI_EC_UDELAY); lines to the acpi_ec_transaction_unlocked() function.
I'll do some more testing and report my experiences the next days.

So if I understand this right, acpi=noirq doesn't do anything right now (other than disabling the brightness control)?

On a semirelated note, they are testing yet another patch at that kernel.org bug report.

this works for me without any kernel option.
i'm testing kernel 2.6.28 from Ubuntu Jaunty and 2.6.29-rc3.

I try to create a ppa for the kernel, but i get errors every time ;-)

It's still looking good but sometimes it takes a while to break.

If it's still looking good in the Morning I'll post some instructions.
It's not too bad, but it's probably more than a lot of folks want to do every time the kernel is upgraded.

If this works it would really be nice if the developers would make the affected parameters available
as kernel options so we could just put the changes in menu.lst & be done with it.

Will Ubuntu upgrades overwrite this or will the kernel be upgraded when this ppa is??

i just increase the version number...so it will be overwritten if a new kernel comes out.

we hope to get this patch into the kernel so it will be fixed in the next kernel version. hopefully the ubuntu maintainers add this to the jaunty kernel.

I see now, you bumped it from 2.6.27-11.27 to 2.6.27-11.28
I like the way that works.
If Ubuntu upgrades to something like 2.6.27-1X.YZ then you can make a 2.6.27-1X.YZ+1

Yeah, if Ubuntu puts it in their jaunty kernel that will be great.
With any luck it will make it to the kernel.org kernel eventually.

He changed ACPI_EC_UDELAY from 100 to 500 and then added the delay to many additional spots in the code.
I'm a little nervous about adding all that delay especially inside a spin_lock, they are only supposed to last for a few instructions.
Keep an eye out for anything strange.

If you still want directions on patching the kernel let me know.

After loading BadBull's ppa you can get his source by:

There aren't near as many delays as in the original patch and no delays in a spin_lock.

the patch from the ppa has only one delay...
for me it works, but at the kernel bug site is a commend from a user who had a problem with it.
I'm a bit confused now, i reverted all patches and build a new image, but it works as well.
please test the ppa kernel as much as you can, so we get a good feedback if the changes really work.

So far, so good.

I'm looking at your diff file
linux_2.6.28-6.17-1_2.6.28-7.21.diff
and noticed there are no changes for ec.c but there are changes for battey.c

Does that also fix the problem??
Is that the patch that will probably make it into jaunty??

this include the first patch with all the delays also in the spinlock.

Yes, the ONLY kernel it ever worked on was Gutsy 64-bit. This was Ubuntu's first 64-bit real-time kernel. The one before and after was *not* realtime.

I've tried our current real-time kerenls, but they do not work.

And maybe the real-time think is a red herring.

I don't really know what the additional delay does, but I suspect it just makes some combination of events less probable.

Hopefully the probability is very low :confused:

maybe the patch doesn't work 100% but just 90%. so its better than nothing ;-)

After not being on my Daru2 for a while, I wanted to catch up with the party and install the fix.

One problem: I can't figure out how to. I've added the ppa, added the key, did the update/upgrade. Now what? It didn't look like it was included in the packages gotten on the upgrade. I can't seem to "find" something called linux - 2.6.27-11.27 anywhere via synaptic or aptitude.

So can someone hold my hand through this? What does an unknowledgeable end-user need to do to get this working?

Thanks!

if ubuntu 9.04 will not include the patch i'll update the ppa for every kernel update. otherwise you can install the vanilla kernel as deb package from http://kernel.ubuntu.com/~kernel-ppa/mainline/
these packages are build from the original source without any patches from ubuntu. all versions from 2.6.29-rc5 should include the patch.

However, I'm still having the no-battery/high temp bug in acpi. This *may* have fixed glitches I was seeing with my touchpad. I see that other users have still had problems with acpi after applying this patch on 32bit Intrepid. Will upgrading to Jaunty (and installing patch) work better?

are you sure you running the right kernel? on other users the problems appears only after dates. please print the output of

uname -r provides 2.6.27-11-generic and I have that version locked (in Synaptic) to the ppa0 version, which I think is yours.

I haven't had the power management issue reoccur since the first day, but my touchpad is acting up again today. I know these problems are hard to diagnose when it is a day-by-day issue.

I've been trying to watch dmesg for things that might be a hint into what appears to be a acpi/mouse issue. In the following snippet, are either of the first two lines indicative of anything?

I realize that the touchpad issue, the power management work-around, and the CE and ACPI: EC lines might all be unrelated, but if any of these printouts are unique to me, I figure they might be related to the problem.

ackey,

Does your touchpad ever quite working?

ackey
March 25th, 2009, 06:43 PM
So far it hasn't stop responding permanently, but it is still glitching - not responding for a second, usually my music skips too. In the past (previous touchpad, Ubuntu versions, kernels...) glitching would eventually lead to constant fake signals to mouse and keyboard - my computer would look possessed. The glitching used to be accompanied by ACPI failures (battery and temp) and a spike in my CPU usage chart. Now (with this kernal modification) I don't seem to be getting those now.

But the mouse is "losing sync" a few times a minute sometimes, which makes use difficult. I've found that if I use Fn-F3 to disable the touchpad and use an external mouse I don't see these issues.

The last few times I've seen these errors on a DarU2, the touchpad was on its way out.

Does anybody else using the kernel patch see these messages?

jdb
March 25th, 2009, 08:28 PM
if ubuntu 9.04 will not include the patch i'll update the ppa for every kernel update. otherwise you can install the vanilla kernel as deb package from http://kernel.ubuntu.com/~kernel-ppa/mainline/
these packages are build from the original source without any patches from ubuntu. all versions from 2.6.29-rc5 should include the patch.

I just loaded loaded kernel 2.26.29 & got:

15:24:38 ~ dmesg | grep "ACPI: EC"
ACPI: EC: Enabling special treatment for EC from MSI.
ACPI: EC: Look up EC in DSDT

ACPI: EC: GPE = 0x17, I/O: command/status = 0x66, data = 0x62

Hi Badbull,

I've installed the patched kernel from the ppa.
I'm running the latest Intrepid kernel from there

uname -r states: 2.6.27-14-generic

In Grub I removed the ACPI=NOIRQ line and The battery is disabled + temp off the charts (146c)

Should it be enabled with the patch ?

How do I make sure that the patch works ?

dmesg gives this:


[ 0.492808] ACPI: EC: Look up EC in DSDT
[ 0.516241] ACPI: EC: non-query interrupt received, switching to interrupt mode
[ 0.520214] ACPI: EC: GPE = 0x17, I/O: command/status = 0x66, data = 0x62
[ 0.520214] ACPI: EC: driver started in interrupt mode


I tried installing the Jaunty kernel on my Intrepid laptop, but dependencies aren't resolved.

Thnaks,
Idan.

hi idan,

sorry for my absence. MSI sucks on repairing the webcam...

first you should try
dmesg | grep "ACPI: EC"
if you get something like "Enabling special treatment for EC from MSI." the patch is in the kernel.

because i'm not on intrepid anymore, the intrepid package of the ppa is may outdated (mine is 2.6.27-11).
I'll update this in the next weeks.
otherwise you can install the mainline kernel (unpatched vanilla kernel as deb package).
it will include the patch since 2.6.29
http://kernel.ubuntu.com/~kernel-ppa/mainline/
take 2.6.29.4

laserline
May 24th, 2009, 01:23 PM
Hi,

Thanks for your response, I already got the mainline kernel (2.6.29.3) - I will update to 2.6.29.4
The patch works, and it's good to have the battery monitor back :)
Does the 2.6.29 kernel fix the sqlite issue ?

Thanks,
Idan

I just upgraded to jaunty (hoping all of my problems would be fixed) and was still seeing power management issues. I tried the mainline 2.6.29 kernel, but I'm not seeing the message above. I haven't seen any strange behavior for the 15 minutes since starting with the new kernel, so perhaps it is working.

If this does start failing, what is the best known method for dealing with ACPI on Daru2 running jaunty?

I'm running the 2.6.29 kernel with Arch Linux on a Daru2, power management works correctly & I get the "... EC from MSI" message.
I've also tried the vanilla kernel from kernel.org and get the same results.

I once installed a 2.6.29 kernel in Ubuntu & it worked correctly also.
I once installed BadBull's patch & it worked good too.
Sometimes patches break with new releases, I haven't tried it recently.

I'm not familiar with "mainline 2.26.29 kernel", how did you install it???

I got the kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/. It just intalled with dkpg, which I can handle. I hadn't realized there was a difference (as there apparently is) so I had gone for the one that seemed simpler.

I started trying to compile the kernel from kernel.org, but I have absolutely no clue what I am doing. Is there an easy way to figure out the answers to the config questions? I was just using the default ones, but there isn't a default for the RCU configuring.

That's a cool directory, I didn't know about it.

I just downloaded linux-source-2.6.29_2.6.29-020629_all.deb and untarred the source code.
The following is from that source so it looks like the patch made it into code OK.


14:40:05 acpi grep MSI ec.c
static int EC_FLAGS_MSI; /* Out-of-spec MSI controller */
if (EC_FLAGS_MSI)
pr_info(PREFIX "Enabling special treatment for EC from MSI.\n");
EC_FLAGS_MSI = 1;

You might double check that you loaded the kernel itself & not just the headers.
You can check what you are running with:


uname -a

I've certainly never tried to reflash my bios (I doubt it is something I can accidentally do through stupidity). I see it is determining the EC_FLAGS_MSI by

I asked my partner (who also has a DarU2) to check his and he found:
BIOS Build A1221IG6 V1.10 5/28/07

So the A1221IG6 isn't particularly identifying, but somehow we have very different versions and dates. He got his computer 6 months or so after I did, but I sent mine in to System76 for some maintenance in Jan of 2009. So perhaps they loaded a new BIOS version?

I know my partner claims to have no problem with power management.

HA HA that's easier than I was thinking.

My BIOS matches your partners exactly.
I think you've gotten to the root of the problem but I don't know the fix.
You could hack the ec.c code to load the fix unconditionally but that would be a pain every time there was a kernel update.

I wonder if there's any way to flash the BIOS to what it was originally??
Maybe Tom Aaron knows.

It's hard to say for sure what the BIOS was originally. Probably when we sent your machine in for the touchpad problem they flashed the BIOS to bring it up to date.

Your partner's BIOS, version 1.10 was definitely one of the first versions, though. I remember there were some imaging problems with it, so we started updating to the next version... (1.2**, I think).

I find it curious your partner has no power management problems with version 1.10, though.

ackey
June 9th, 2009, 06:31 PM
So this new BIOS means I can't use the existing patches for power management?

I wouldn't mind hacking the ec.c code, but compiling the kernel terrifies me. What other options might there be?

First of all, this bug (the power management bug) and the suspend bug are separate. Fixing this one doesn't solve suspend.

Second, I wouldn't expect System 76 to start providing this patch at this point. It was fixed in the mainline kernel and will finally be included in the Karmic kernel (only a few weeks away from release now), at which point a patch will no longer be needed.

That said, I'm pretty disappointed that System 76 never provided this patch in the driver. I haven't been able to update my kernel in over 3 months now and before that I was relying on a 3rd party PPA for updates. Surely this is the kind of thing System 76 should be taking care of?

That said, I'm pretty disappointed that System 76 never provided this patch in the driver. I haven't been able to update my kernel in over 3 months now and before that I was relying on a 3rd party PPA for updates. Surely this is the kind of thing System 76 should be taking care of?

I fully agree. Disappointing.

I didn't realize that it was fixed in Karmic, that's good news. Thanks for the heads up.
