Oh and could you please post the full content of the system log
(relevant section only). Grepping for dme doesn't provide all the
information.
Thanks

Looks like you run into the same issue as
http://bugzilla.kernel.org/show_bug.cgi?idf49.
I'm not an ACPI expert, by no means. I would take this to the
linux-acpi mailing list.
However, it looks to me like your DSDT has references to _TZ_.THRM
which is also declared external. So something else needs to be loaded
(?) that provides this method. Is it SSDT? I don't know, I don't even
know what SSDT is. I can only suggest to follow what one person
suggested in the bugzilla bug report: Try loading the cpufreq driver
and check if the error goes away.
As for the dme1737 errors. Can you send the output of 'dmesg -s64000'?

Ok, it looks like every time you get the ACPI errors, a subsequent
dme1737 access returns a non-zero status (SMBus busy (02)) which in
turn results in a successful reset. So far so good. The 02 means the
following (from the ICH6 spec):
[... This bit can only be set by termination of a command. INTR is not
dependent on the INTREN bit (offset SMBASE + 02h, bit 0) of the Host
controller register (offset 02h). It is only dependent on the
termination of the command. If the INTREN bit is not set, then the
INTR bit will be set, although the interrupt will not be generated.
Software can poll the INTR bit in this non-interrupt case.
0 = Software clears this bit by writing a 1 to it. The ICH6 then
deasserts the interrupt or SMI#.
1 = The source of the interrupt or SMI# was the successful completion
of its last command. ...]
Now the problematic case is where you get a 'SMBus busy (01)' status .
The following reset does not succeed which makes sense, since the i810
driver is trying to clear a read-only bit. From the ICH6 spec, status
01 means:
[... HOST_BUSY — RO.
0 = Cleared by the ICH6 when the current transaction is completed.
1 = Indicates that the ICH6 is running a command from the host
interface. No SMB registers should be accessed while this bit is set,
except the BLOCK DATA BYTE Register. The BLOCK DATA BYTE Register can
be accessed when this bit is set only when the SMB_CMD bits in the
Host Control Register are programmed for Block command or I2C Read
command. This is necessary in order to check the DONE_STS bit. ...]
So in this case the SMBus controller is busy doing somebody else's
work! Every access by the dme1737 results in a unsuccessful reset
until the next ACPI error comes along. From that point on the SMBus
controller is not busy anymore and accepts subsequent dme1737
accesses. Smells like a collision between the dme1737 driver and ACPI.
So the bottom line is you have a broken BIOS causing the ACPI errors
and I believe ACPI and the dme1737 driver collide.
Here are a few suggestions of things you can try:
1) unload the fan and thermal modules and check if the dme1737 and
ACPI errors go away.
2) load the acpi_cpufreq module (don't know if your HW is supported
though) and check if the ACPI errors go away.
3) load the thermal module and do 'grep ""
/proc/acpi/thermal_zone/*/*' and send the output to the list.
4) send me the DSDT table (in private): cat /proc/acpi/dsdt > dsdt.aml
5) test Jean's patch that detects ACPI and hwmon collisions. Jean:
where can he pick it up?

Nope, couldn't find anything, sorry.

The dme1737 errors are because the SMBus is busy. The SMBus is busy
because ACPI is accessing it (I believe). The ACPI errors are due to a
broken BIOS/DSDT or more precisely due to a missing _TZ_ method. I
read somewhere (I believe on the linux acpi mailing list) that the
method might become available when loading the acpi_cpufreq module.

You can specify acpi=ht to just enable enough ACPI for hyperthreading.

OK, so it's definitely ACPI that interferes with the dme1737 driver.
Not good. I'm surprised that removing the fan and thermal modules
didn't get rid of the ACPI errors. But then again I'm not an ACPI
expert so don't really know how it works and what to expect...
I recompiled the DSDT that you sent me and it's definitely broken. You
can try to fix it but again I don't know what you can expect from that
exercise. I also took a closer look at the DSDT and there's code that
accesses the dme1737 all over the place. It mocks around with temp
limits and PWM duty cycles and more. It's definitely *not* safe to use
the dme1737 driver, it's interfering with ACPI regulating the fans
based on the measured temps. Now why ACPI is controlling the fans
instead of letting the dme1737 chip take care of it is beyond me...
You'd have to ask the smart designers at ASUS :-)
Bottom line, I think you have 3 options:
1) Disable ACPI and use the dme1737 driver. In that case you loose the
automatic fan control unless you set it up yourself. Dangerous, you're
interfering with the way the machine is designed to work and might fry
it.
2) Take it to the ACPI mailing list and try to figure out what exactly
ACPI is doing and what needs to be fixed to get rid of the ACPI errors
(that still doesn't fix the dme1737/ACPI conflict issue).
3) If you're brave, you can keep using the dme1737 driver, ignore all
the erros and hope and pray it doesn't interfere with ACPI in a way
that puts the HW at risk.
Jean: Do you know where the whole ACPI/hwmon conflict issue is at? Do
we know what the problem is, when it occurs, and how to get around it?

There's nothing fundamentally wrong with this, if the ACPI
implementation is correct. Why require an OS driver if they can do the
same in ACPI and it works on all OSes without user interaction?
Of course this also means that the user has almost no control over
what's going on, which is alright if things work well, but becomes a
problem if they don't. The worst thing is that almost all the time, the
ACPI stuff only exposes a small subset of the hardware monitoring
chip's features, which is very frustrating for computer enthusiasts.

The patch I posted (which will be in the next -mm kernel also) attempts
to detect the conflicts, and the hwmon and i2c (bus) drivers will
cooperate and refuse to load when a conflict is detected. This approach
relies on the fact that ACPI is supposed to declare which ports it may
access at run time. This may yield false negatives (if ACPI doesn't
declare port usage properly) and false positives (if ACPI declares
ports that it doesn't actually use.) So we're waiting to see the effect
of the patch on a large number of systems, if it is acceptable it will
go upstream.
It would be great if Borislav could try either my patch or the next -mm
kernel, and report whether the conflict is detected or not.
What we will do next, I'm not sure. In some cases it might be possible
to synchronize the hwmon driver accesses with the ACPI accesses, then
we can get both to cooperate. In other cases it probably won't be
possible and we'll have blacklist the hwmon driver, I fear. There is
also at least one known case where an "ACPI hwmon driver" can be
written on top of the ACPI code to expose all the features as regular
hwmon drivers do. All in all, the outcome will probably be highly
dependent upon the machine, as every ACPI implementation is different.
I'll keep the list updated when things progress, of course.

What I meant by my comment is that I don't understand why they don't
make use of the automatic fan control feature of the dme1737 chip.
That would be much simpler (setting up a couple of registers) and
wouldn't require implementing a closed-loop control algorithm SW. It's
an ASUS board and they do it for other motherboards, so why not on
this one? Maybe it's an HP requirement, I don't know...

He claims he tested it and it didn't do anything. Bobby: Can you elaborate?

How can we achieve cooperation between the two?

Uh-huh... Based on the motherboard/system type? How does that work?

Sorry, I had misunderstood your question. I had not realized that the
ACPI code was implementing software fan control. I agree with you that
it's silly to do in software something that can be done much more
efficiently and reliably by the hardware. I have no clue why they did
that, but that's unfortunately not the first time I see this.

There's a mutex protecting the execution of AML code. If the hwmon
driver takes it when accessing the chip, at least we know that there
won't be conflicting I/O accesses. But this doesn't solve the possible
functional conflict if ACPI is doing really weird things. Maybe we'll
want to turn the hwmon driver read-only in some cases.

That would be based on DMI data, I think. That's the last resort, I
hope that we can avoid blacklisting in most cases.
But it's really only ideas at this point, I did not start writing code
and many things can still be discussed on a case-by-case basis. I'll
try to fix my own system first, when I get time, and once this is done,
depending on the result, I'll see what I can do for other systems.
