PROBLEM: ACPI crashes (2.6.2-rc2-mm1)

[Georg C. F. Greve]

[-- Attachment #1.1: Type: text/plain, Size: 502 bytes --]

Hi all,

still having problems with ACPI on ASUS M2N. [1]

With linux-2.6.2-rc2-mm1 with acpi4asus from CVS as of today:


Suspending to disk (S4) suspends just fine. It also finds the file and
reads the data back into active memory, as well. But when it comes to
the message

 "Waiting for DMAs to settle down." 

the machine suddenly crashes (reboot).

I tried to get some debugging output by not having swap mounted when
trying to suspend so it would have to come right back up. Here is the
output


[-- Attachment #1.2: Type: text/plain, Size: 619 bytes --]

Suspend to RAM (S3 via 3bios) seems to suspend the machine just
fine. Only the power button brings it back up, but when it comes back
up it seems to hang -- cannot tell as even though the disk seems to
have come activity the screen remains black and network apparently
doesn't come up.

Hope this helps tracking down the ACPI problems.

Help appreciated, if more input is needed, please let me know.

Regards,
Georg

it seems the same on my M3N, I attached some mails I already sent to
this list, which solved the problem for S4, maybe you could give it a
try. IMHO is still an Intel 855GM problem.

As soon as I'll come back home, I'll try again on my M3N.

[the following is for ASUS L3800C]
Same here for USB (actually, unloading {usb-,}uhci suffices, 2.6 doesn't
hang though). ALSA doesn't seem to care in my case.
About the shutdown: it is likely that a PWRF event is issued after resume
like in my case, kill acpid prior to suspending and see if it makes any
difference (I reported the PWRF problem here a while ago, but have
received no feedback so far).

Kill X and unload AGP or use Nigel's patches from swsusp.sf.net.

ok, I tried the following without the AGP/DRM modules (specifically,
'agpgart', 'intel-agp' and 'i830'):

I got a resume on my ext3 partitions, but the swap isn't lost

the resume I can successfully resume or shutdown :-)

I agree with this. I see exactly the same behavior on my Gateway 200X, which
has an Intel 855GM chipset. I'll try the suggestions from the appended emails
later to see if they help.

For the record: Several of us over on the swsusp list appear to have
rouchly the same problem: With some effort and fiddling (as described in
the previous mail), swsusp2 works for console and even from
unaccelerated X, but whenever DRI ang AGP is enabled it resume will
crash. Some of us think this is related to the agpgart rewrite for
2.6.x, but our patching so far have not made any difference. There seem
to be resume code in the intel-agp plug which we have tried to duplicate
in sis-agp, but it appears not to be called during resume... Obviously,
I don't really know enough about how it is supposed to work so we are
just experimenting for now.

I also seem to have occasional PCMCIA+fan collisions on my ASUS L5800C,
(mentioned earlier on this list) but I don't really thing that is
related, but some things certainly more or less woo-doo... ;-)

HW details and some experiences here:

just for the record, in my case, 'swsusp' (normal, not the 'swsusp2' by
Nigel Cunningham) works *perfectly* without DRI and AGP. 'Perfectly'
means that I can suspend from X (obviously, unaccelerated) and
successfully resume on X with the USB and ALSA (0.9.7) modules loaded
(but as I don't have any USB devices here, I can't tell if USB working
let you suspend/resume). This is a starting point, I hope, even for the
'swsusp' mode.

I never tried 'swsusp2', I could give it a try if necessary. The same
for 'pmdisk'.

Well, I could try on 2.4.23 to find out if the problem is 2.6 or not.
Anyway, what is strange is that the problem is on an Intel graphics
chipset, so it the 'intel-agp' has some resume code, it /should/ work.
And this isn't the case :-(

Re: PROBLEM: ACPI crashes (2.6.2-rc2-mm1)

[Greg Sarjeant]

Hi,

  Just wanted to add my experience. I was able to suspend to disk and
resume just fine from a console with the following configuration on the
Gateway 200X.

kernel 2.6.1
agpgart module loaded
intel_agp module loaded
i830 module loaded
swsusp compiled into the kernel
ACPI sleep states compiled into the kernel
suspend with 'echo 4 > /proc/acpi/sleep'

   When I tried this after starting X with startx, I got the reboot loop
described by others. I figured I'd give it a shot, since the AGP modules
didn't interfere with the console suspend/resume. Ah well. 

   Interestingly, starting X and then dropping back into a console
caused problems, too. I didn't get stuck in a reboot loop, but the
resume just hung. It did get past the 'Waiting for DMA to settle down'
message, though. I can't remember now exactly what it said, but it
seemed to be mostly done. I had to do a hard reboot to get it back, and
then I had to do the 'noresume; mkswap; swapon' routine.

   I haven't tried unaccelerated X, since the AGP modules seem to be
loaded regardless of what I do (remove the agpgart alias in
/etc/modules.conf, remove X from default runlevel, etc) and I cannot
unload them. I guess I should try compiling a kernel without AGP support
at all next.

   Thanks,
    Greg

Re: PROBLEM: ACPI crashes (2.6.2-rc2-mm1)

[Alexei Gilchrist]

Hi,

On my Panasonic W2 (also with 855GM) swsusp2 will hang on resume when
running 2.6.1 (from X). Running 2.4.23 will work happily --- from console,
from X with vesa driver and X with i810 driver.

I've had mixed results with USB on resume, which can usually be fixed by
unloading the modules and reloading them. I'm not using DRI.

cheers,

Alexei

Yep, sounds like we are in the same state. I've not been around long
enough to know the whole history for sure, but it appears that Nigel has
worked for quite some time on swsusp on 2.4 and Pavel has worked on a
2.6(pre) as different branches some original "swsusp". Now that Nigel is
going 2.6 the two branches are rather different and hence Nigel's 2.6
version is called swsusp2 while his 2.4 version is just swsusp. Somewhat
confusing... So far Nigels stuff is only available as a patch.

Well, I can say that my system suspends and resumes flawlessly from
2.4.x with accelerated X - I've had several hundreds of cycles since I
installed (early autumn). No crashes at all, but a handful of failed
suspends while hunting down some incompatible drivers - for instance the
 LinuxAnt driver for the builtin wireless card...

yes, this is what I know... IMHO the /problem/ is that Nigel's project
site is 'swsusp.sf.net', so far confusing for a newbie (who doesn't know
the whole story).

> suspends while hunting down some incompatible drivers - for instance the
>  LinuxAnt driver for the builtin wireless card...
The same here if I leave 'ndiswrapper' loaded. IMHO the problem with all
the NDIS wrapper (Linuxand and NDISwrapper) is that they aren't Linux
native drivers, so it could be more difficult to implement power
management. Anyway, I'll pass to a native Linux Intel Centrino driver,
as soon as it will be one: Jon Lech Johansen started one which could
read the MAC address, but his site is no more on and I can't find other
info :-( (BTW, I don't have the capacities to continue his work)

Re: PROBLEM: ACPI crashes (2.6.2-rc2-mm1)

[Greg Sarjeant]

Looks like this didn't get through last night. Let me try it again.



Hi,

  Just wanted to add my experience. I was able to suspend to disk and
resume just fine from a console with the following configuration on the
Gateway 200X.

kernel 2.6.1
agpgart module loaded
intel_agp module loaded
i830 module loaded
swsusp compiled into the kernel
ACPI sleep states compiled into the kernel
suspend with 'echo 4 > /proc/acpi/sleep'

   When I tried this after starting X with startx, I got the reboot loop
described by others. I figured I'd give it a shot, since the AGP modules
didn't interfere with the console suspend/resume. Ah well. 

   Interestingly, starting X and then dropping back into a console
caused problems, too. I didn't get stuck in a reboot loop, but the
resume just hung. It did get past the 'Waiting for DMA to settle down'
message, though. I can't remember now exactly what it said, but it
seemed to be mostly done. I had to do a hard reboot to get it back, and
then I had to do the 'noresume; mkswap; swapon' routine.

   I haven't tried unaccelerated X, since the AGP modules seem to be
loaded regardless of what I do (remove the agpgart alias in
/etc/modules.conf, remove X from default runlevel, etc) and I cannot
unload them. I guess I should try compiling a kernel without AGP support
at all next.

   Thanks,
    Greg

Someone found that copying pages backwards helps for him. Very strange
but you might want to try it.

The first part is right - Pavel and I have the same original code base.
However the last needs some correction. Suspend2 is available for both
2.4 and 2.6, and it's the same core code for both, so there shouldn't be
any confusion. I intend to work toward getting the 2.6 version merged,
but this will take some time as I'm just stopping working full time on
Suspend, and so it will go on the backburner. I hope to try to do a
patch every day or two for LKML.

Regards,

Nigel

That might indicate a cache configuration problem.

Could you please redescribe that issue. Maybe bugzilla.kernel.org
is a good place for bug-report.

we need to narraow down to codes/component causing this crash?

Does it work?

Why do you have such intuition?

I have included the description below. I'll be happy to file it on
bugzilla, but I was a bit reluctant as I have to admit that I am no
longer bleading edge (this is my "real work" system and I sorely need
swsusp2 working under 2.6.x before I upgrade). I *WILL* experiment if
anyone has any specific ideas on how to get this to work, but I don't
really expect to NEED the GSM card until late spring - and I expect to
go 2.6.x before then.

[ Original description follows: ]

I've encountered a problem which I *THINK* i ACPI related, but I've not
enough ACPI experience to understand how to get around it. Any hint
appreciated.

I'll file it as a proper kernel bug if you think it more appropriate.
Here is a quick rundown of what I've found out:

* My base installation is described pretty detailed here:
http://www.xms.se/~zap/linux/asusl5800c.html
As you can see it has worked pretty well for quite some time and hence
my kernel etc is not quite bleading edge anymore (though I follow Debian
testing for everyting else).

* $ cat /proc/acpi/info
version:                 20030813
states:                  S0 S1 S3 S4 (swsusp) S5

The problem I've encountered lately is related to using a Nokia
CardPhone in my PCMCIA slot. Several other cards have work OKish - at
worst, an ethernet card wouldn't work at all (forgot the name, but it
was multifunction and was iffy anyway) and in one case a wavelan card
(orinoco) would only work in the upper slot. This is significantly worse:

Initially I just plugged it in without a SIM card and got some "Resource
unavailable" problems - fiddling with the /etc/pcmcia/config-2.4 file
appeared to help, though it was somewhat odd that specifying low IRQs
(say 4,5,6) still reported 10 or 11 in dmesg, but at least it appeared
to work.

I now also tried with a SIM card in place and noticed that the FAN would
stop a short while after inserting the card (I can hear the GSM
negotiations as noises in the speakers) when some IRQs where used
and then I had messages such as these in dmesg:


ttyS17 at port 0x0100 (irq = 11) is a 16550A
Trying to free nonexistent resource <00000100-00000107>
Trying to free nonexistent resource <00000100-00000107>
   ACPI-1121: *** Error: Method execution failed [\_TZ_.FAN0._INI]
(Node dffe9520), AE_AML_PACKAGE_LIMIT
   ACPI-1121: *** Error: Method execution failed [\_GPE._L16] (Node
dffe28a0),
AE_AML_PACKAGE_LIMIT
   ACPI-0297: *** Error: AE_AML_PACKAGE_LIMIT while evaluating method

   ACPI-1121: *** Error: Method execution failed [\_TZ_.FAN0._INI]

   ACPI-1121: *** Error: Method execution failed [\_GPE._L16] (Node
dffe28a0),
AE_AML_PACKAGE_LIMIT
   ACPI-0297: *** Error: AE_AML_PACKAGE_LIMIT while evaluating method
[_L16] for GPE[ 0]
ttyS17 unloaded

Unplugging the card before the temperature gets too high seems to help
as the fan restarts typically after less than a minute.

I then tried acpidump and alltough I don't really understand all of it,
it sure hinted that an _INI method for FAN0 which may be called from
_L16 within the _GPE scope, but I can't really see how this should
suddenly stop working when I plug that particular card in.

Still, some combos of IRQs and port selections appeared to work at the
time and I would be able dial up using minicom and/or kppp.

At this stage I realized that debian demends that I'm part of the dip
group and for sanity reasons I decided to logout and reboot to make
sure everything was in a sane state - apparently it wasn't:

kppp will now sort of seem to work and the fan will run OK, but after a
minute or so the system will suddenly go wild:

- In one case, X died and I could only type (but got no response) in the
old X vt.
- In another case, X again died and a few messages flashed past too
quickly to read and then it was powered off.
- In a third case, a lot of info flashed past in an Oops dump (sorry,
wan't able to catch it).

To me it seems to be some kind of ACPI/PCMICA clash, but I have no clue
how to solve it. I had intended to wait for a couple of more weeks
before going 2.6.x as swsusp is somewhat critical to my daily work and
it seems not quite stable for 2.6 yet (considering even Nigel himself
runs 2.4 for development...)

Here's a bit more info:

$ cat /proc/interrupts

Because if it works backwards but not forwards, the major difference is
the caching and pre-fetching.
