linux-next: ACPI I/O resource conflicts warning

[Gabriel C]

Hi all ,

I've noticed on linux-next from today the following ACPI warning:

...

[4294023.308622] ACPI: PCI Interrupt 0000:00:1f.3[C] -> GSI 18 (level, low) -> IRQ 18
[4294023.308622] ACPI: I/O resource  [0x400-0x41f] conflicts with ACPI region SMRG [0x400-0x40f]
[4294023.316478] ACPI: Device needs an ACPI driver

...

dsdt.dsl from my motherboard can be found there:

http://frugalware.org/~crazy/ASUS_P5E-VM_DO/dsdt.dsl

full dmesg:

http://frugalware.org/~crazy/dmesg/DMAR/dmesg

Please let me know if you need more infos.

Best Regards,

Gabriel C

You use libsensors and the sensor you use is also declared and possibly
used via ACPI.

Maybe you could open a bug report on bugzilla.kernel.org and post
acpidump and dmi output (not only dsdt) there. Then we could collect
affected BIOSes at one central place for further evaluation and
discussion.

Not really , lsmsensors was not running and no modules loaded for my sensors but yeah when I start it another warning
pops up ( this one I've reported to lm-sensors mailing list )


w83627ehf: Found W83627DHG chip at 0x290
ACPI: I/O resource w83627ehf [0x295-0x296] conflicts with ACPI region HWRE [0x290-0x299]

Could be your SMBus controller then, we have these checks in both hwmon
drivers and i2c bus drivers... Check what appears at 0x400
in /proc/iports.
