ACPI Exception (evregion-0422): AE_ERROR, Returned by Handler for [PCI_Config] [20090320]

[Justin Mattock]

I posted this error a few weeks ago, but had no response.
So after a few weeks of looking at this, I wanted to find out if
this is safe to see this, or should I be concerned:

[    5.868418] ACPI: Power Button [PWRB]
[    5.868547] input: Sleep Button as
/devices/LNXSYSTM:00/device:00/PNP0C0E:00/input/input4
[    5.868621] ACPI: Sleep Button [SLPB]

[    6.093614] ACPI: Transitioning device [GFX0] to D0

I did do a dsdt dump, and looked for any errors
but none had shown up.
kernels that I have seen this are 2.6.29 -
2.6.30-rc5

please file a new bug report at
http://bugzilla.kernel.org/enter_bug.cgi?product=ACPI
and attach the full dmesg output and acpidump there.

thanks,

alright(Ill have to do that when I get a chance)
As for the error message after looking into it more today
I notice this message fired off as soon as I compiled
and loaded the nvidia module.

It looks like the nvidia driver is triggering an evaluation of the _PS0 
method on your graphics hardware. This ought to just power up your 
hardware. In the process it's trying to write to PCI configuration 
space, and some kind of error is being generated as a result - the debug 
output doesn't obviously make it possible to work out what.

If your graphics hardware still works then it's not an issue, but 
there's the possibility that this is a Linux bug which might generate 
real problems in some other situation.

right now with 2.6.30-rc7(I'll have to load
*-rc8 in the next few days)
Everything seems to be running o.k.
(even with this error message)
under nvidia-settings the temperature
is at a comfortable number.

There is some issues when watching
movies on certain sites(but I think this is gtk+
related)
As for the kernel, I didn't check to see is acpi's video module
is loading or built-in(will look when I get a chance),
quit possibly causing some interference.
(but probably not)

In any case my main concern with the gpu is
to make sure that the temp stays at a good level,
and so far It has.
