Description Jan "Yenya" Kasprzak 2005-02-02 09:00:38 UTC

Hardware Environment: Asus M6R Laptop (http://www.fi.muni.cz/~kas/m6r/
Software Environment:
Problem Description:
I am experiencing various ACPI problems with my Asus M6R laptop:

1. When using 2.6.8.1 or 2.6.9, I can use ACPI (read battery status, switch the
modem LED on/off using echo [01] >/proc/acpi/asus/mled, etc.). With newer
kernels (tried some 2.6.10-rcX, 2.6.10, 2.6.11-rc2-bk9 I get ACPI errors on boot
and I am not able to read battery status or switch modem LED on/off.
The relevant part of the "dmesg" of 2.6.11-rc2-bk9 during boot is the following:

PCI: Using ACPI for IRQ routing
** PCI interrupts are no longer routed automatically.  If this
** causes a device to stop working, it is probably because the
** driver failed to call pci_enable_device().  As a temporary
** workaround, the "pci=routeirq" argument restores the old
** behavior.  If this argument makes the device work again,
** please email the output of "lspci" to bjorn.helgaas@hp.com
** so I can fix the driver.

2. ACPI S3 does not work in 2.6.8.1 and 2.6.9 (the laptop suspends itself, but
apparently goes to a "power off" state - no LED is on. When I power it on again,
it is a normal cold boot. With 2.6.11-rc2-bk9 the S3 state works (the power LED
starts blinking, but after pushing the power button the system does not resume
itself) 2.6.11-rc2-bk9 with acpi_sleep=s3_bios boot parameter is the same as in
2.6.9 (the laptop goes off instead of suspending to RAM).

I will attach my source and binary DSDT in a moment.

Comment 4 Jan "Yenya" Kasprzak 2005-02-10 02:09:01 UTC
Hmm, it seems my AE_AML_BUFFER_LIMIT fix was not correct, and it is in fact the
kernel bug - the fix is described by Robert Moore at
http://sourceforge.net/mailarchive/message.php?msg_id=10775149.

The "Handler for [EmbeddedControl] returned AE_TIME" error remains unfixed,
though. I have found that 2.6.10-rc1-bk11 is OK, but 2.6.10-rc1-bk12 has this
problem.

Part of diff between 2.6.10-rc1-bk11 and -bk12

I've diffed the linux-2.6.10-rc1-bk11 and -bk12 trees, deleted most of the
diff, and now I have the attached patch, which, when applied to 2.6.10-rc1-bk11
makes ACPI on my laptop not working (AE_TIME errors), and, when removed (patch
-R) from 2.6.10-rc1-bk12, makes ACPI working on my laptop.

I just don't see what is the problem - the patch itself is a
sysfs/uevent/hotplug update. Nothing related to ACPI, I think.
Comment 6 Jan "Yenya" Kasprzak 2005-02-10 08:33:29 UTC
It seems to be some kind of race condition or what - with
CONFIG_ACPI_DEBUG my ACPI does not work even with 2.6.8.1 and 2.6.9,
without CONFIG_ACPI_DEBUG it is OK up to 2.6.10-rc1-bk11. A pretty
Heisenbergish behaviour, isn't it?
Comment 7 Len Brown 2005-02-18 15:05:42 UTC
can you reproduce the problem still wit the latest kernel? 
(ACPICA 20050211) 
Comment 8 Jan "Yenya" Kasprzak 2005-02-23 09:55:03 UTC
2.6.11-rc4 + <kernel.org
mirror>/people/lenb/acpi/patches/release/2.6.11/acpi-20050211-2.6.11-rc4.diff.bz2,
AE_TIME errors still there (and no /proc/acpi/battery/BAT0/* files available).

Sorry for the delay - my laptop just returned from a repair (broken external VGA
port).
Comment 9 Len Brown 2005-03-01 00:10:22 UTC
Thanks for verifying that with ACPICA 20050211 that the AE_AML_BUFFER_LIMIT 
error messages are gone. 
 
Please attach the complete dmesg -s64000 showing the remaining AE_TIME 
error messages. 
 
If you take the same .config and change only the CONFIG_ACPI_DEBUG line 
from 'y' to 'n' these warnings messages go away and /proc/acpi/battery/ 
appers as normal?  This is true for the latest kernel and also all the way 
back to 2.6.8.1?

No. With CONFIG_ACPI_DEBUG I get those failures with all kernels I have tested
- from 2.6.8.1 to 2.6.11-rc4+ACPICA 20050211. Without CONFIG_ACPI_DEBUG it
works from 2.6.8.1 to 2.6.10-rc1-bk11 (and -bk11 + the patch mentioned above).
With anything newer, I am getting the AE_TIME errors.

And it is not only a "battery" falure, because even more things does not work
(ASUS modem LED/wireless LED, reading centrino speed/voltage tables from ACPI
(so speedstep-centrino does not work)).
Comment 11 Len Brown 2005-03-03 19:56:55 UTC
please test the patch in bug #3967 -- a fix for a similar, 
though not identical, failure. 
 
Note that the error messages are disabled when CONFIG_ACPI_DEBUG=n 
(I think one could argue that this in itself is yet another bug...) 
so when we talk about the AE_TIME failure, we need to focus on features 
not working (or always build with CONFIG_ACPI_DEBUG=y)

> please test the patch in bug #3967 -- a fix for a similar,

I've noticed that this patch is included in acpi-20050303-2.6.11.diff.bz2.
However, it does not fix my problem (neither 2.6.11+the patch from bug #3967 nor
2.6.11+whole acpi-20050303-2.6.11.diff.bz2).
 
> Note that the error messages are disabled when CONFIG_ACPI_DEBUG=n

OK, but for me it seems to corellate - the AC adapter status, battery status,
ASUS MLED/WLED, and Centrino voltage/frequency tables do not work for me if and
only if the AE_TIME error is printed. And it is printed both with
CONFIG_ACPI_DEBUG=y and CONFIG_ACPI_DEBUG=n on 2.6.10-rc1-bk12 and newer.

It is entirely possible that I have a faulty hardware or what. I've seen some
users of Asus M6R which have post-2.6.9 kernel with working ACPI on their
laptops. But I have also seen laptops labeled "Asus M6R" with a different WiFi
adapter, so maybe there are different variants of Asus M6R.

kernel .config difference

I have found that with CONFIG_PREEMPT=y ACPI works for me even on
2.6.11+ACPICA-20050303. I have attached the diff between two .configs - the
non-working one (-) and working one (+).

Wasn't CONFIG_PREEMPT=n supposed to be the "safer" option?

Thanks to Arne Brys who sent me a working .config which I was able to compare
to my .config.

Another observation is that with CONFIG_ACPI_DEBUG=y ACPI does not work for me
even with CONFIG_PREEMPT=y (2.6.11+ACPICA-20050303).

And with CONFIG_PREEMPT=y the network card driver seems to drop connection from
time to time (RTL8139), so it is not a long-term option for me.
Comment 15 Jan "Yenya" Kasprzak 2005-03-11 01:08:35 UTC
It may be related to the in_atomic() use problem which Andrew Morton describes in
http://sourceforge.net/mailarchive/message.php?msg_id=11129317.

I have also verified that on other users' Asus M6R laptops the CONFIG_PREEMPT=n
makes the problem appear.
Comment 16 Jan "Yenya" Kasprzak 2005-06-21 14:09:49 UTC
Any progress in this case?

I've upgraded to Fedora Core 4 (gcc-4), and I have the above problem regardless
of CONFIG_PREEMPT settings. I have recompiled exactly the same 2.6.11.3 kernel
which worked for me under FC3, and with gcc-4 it does not work. 2.6.12 does not
work for me (the same AE_TIME errors). 2.6.9 compiled with gcc-4 is OK.

So this is definitely a race/timing condition (even compiler dependent one).
Comment 17 Piotr Keplicz 2005-06-23 04:39:42 UTC
Just to confirm, 2.6.12 compiled with gcc 3.4.3 works fine with CONFIG_PREEMPT
as long it is built with "only needed modules" config. With Mandriva's config
(on a vanilla kernel) errors appear again.

I also use Asus M6R with the latest BIOS.

Any way I could help to sort out this issue?

Comment 19 Owen Marshall 2005-07-14 22:21:10 UTC
I also have an Asus M6R, and can confirm the presence of this bug as previously
described.  I have ACPI working OK on kernel builds up to 2.6.13-rc2 provided I
disable CONFIG_ACPI_DEBUG.

However, 2.6.13-rc3 breaks ACPI, even when CONFIG_ACPI_DEBUG=n ... with that
kernel, I get the following errors:

Jul 15 15:05:45 localhost kernel:     ACPI-0423: *** Error: Handler for

And that's enough to completely disable any ACPI functions on my laptop.

Just to repeat, using identical .configs on 2.6.13-rc2 and 2.6.13-rc3, -rc2
works fine and boots without errors, whereas -rc3 gives the above messages.

Comment 21 Piotr Keplicz 2005-07-30 07:02:29 UTC
With 2.6.13-rc1 and -rc4 "insmod battery" never returns - it rests in the
"uninterruptible sleep" state. The system is still alive, but when loading ACPI
modules during boot, it prevents execution of other init scripts.

Tested with CONFIG_PREEMPT_NONE=y.
Comment 22 Luming Yu 2005-07-30 07:39:39 UTC
Please test ec_polling patch at http://bugzilla.kernel.org/show_bug.cgi?id=4665

Comment 23 Jan "Yenya" Kasprzak 2005-07-31 06:39:08 UTC
I can confirm that the ec_polling patch (modified to apply to 2.6.13-rc4) works
for me, even with CONFIG_PREEMPT_NONE=y and gcc-4 from Fedora Core 4. Thanks!
Comment 24 Piotr Keplicz 2005-08-01 05:58:37 UTC
With "ec_polling" enabled insmod now works fine, but AE_TIME errors are still
here. I've also tried Jan Kasprzak's .config that works fine with his M6R but
without any success.

Note that my M6R has a different CPU: it's a Celeron M 1.4 GHz.
Comment 25 Mark Lipscombe 2005-08-01 20:54:12 UTC
My M6R, which is a Pentium-M 1.70GHz, also still has the same AE_TIME errors
with this patch.

Under FreeBSD, it returns AE_NO_HARDWARE_RESPONSE, so it's something common
between the two, and isn't affected by raising hw.acpi.ec.timeout on FreeBSD
from 100ms to 1000ms.
Comment 26 Piotr Keplicz 2005-08-02 07:39:56 UTC
I've tested Jan Kasprzak's .config with gcc-4.0.1 and the errors are gone.

They appear again if you use Mandriva .config (I can attach it if it's of any use).
Comment 27 N 2005-09-03 07:41:31 UTC
In stable 2.6.13 the bug come back? (debian, Asus m6r)
Comment 28 Jan "Yenya" Kasprzak 2005-09-04 07:11:43 UTC
2.6.13 works for me (with "ec_polling acpi_specific_hotkey" boot options).
Even better, with 2.6.13 the sw suspends work reliably, unlike the previous
releases, where 25-50% of all resumes locked up during switching back to X.

2.6.15 with ec_burst=1 brings AE_TIME errors back.

2.6.16-rc2 + later, no kernel params not even any patches help :(. Burst code is
ifdeffed due to bug 4980.
Each method that fails seems to want to acquire mutex as you can see in my
duplicate bug's attachements.

Please post dmesg for your latest report.
Any difference with ec_intr=0 and ec_intr=1?
Comment 37 Luming Yu 2006-02-26 17:42:01 UTC
I got dmesg at bug# 6111
Comment 38 Luming Yu 2006-03-01 17:41:31 UTC
This bug is re-opened due to bug# 6111 which is due to unexpected call to 
acpi_ec_remve due to failure in acpi_ec_start.
