hi all!

recently i upgraded my kernel to 2.6.29-gentoo-r5. but after the reboot i saw messages that make me wonder about the proper running of lm_sensors:

Code:

Jun 18 18:49:40 area52 i2c-adapter i2c-0: nForce2 SMBus adapter at 0x1c00
Jun 18 18:49:40 area52 ACPI: I/O resource nForce2_smbus [0x1c40-0x1c7f] conflicts with ACPI region SM01 [0x1c40-0x1c45]
Jun 18 18:49:40 area52 ACPI: Device needs an ACPI driver
Jun 18 18:49:40 area52 i2c-adapter i2c-1: nForce2 SMBus adapter at 0x1c40
Jun 18 18:49:40 area52 it87: Found IT8716F chip at 0x290, revision 1
Jun 18 18:49:40 area52 it87: in3 is VCC (+5V)
Jun 18 18:49:40 area52 it87: in7 is VCCH (+5V Stand-By)
Jun 18 18:49:40 area52 ACPI: I/O resource it87 [0x295-0x296] conflicts with ACPI region IP__ [0x295-0x296]
Jun 18 18:49:40 area52 ACPI: Device needs an ACPI driver
Jun 18 18:49:40 area52 k8temp 0000:00:18.3: Temperature readouts might be wrong - check erratum #141


the k8temp issue is ok for me, i already know that the temp might not be correct. but the other messages...
i already unmasked lm_sensors and this installs me version 2.10.8.

can someone help me with this?

thx in advance

Did you use make oldconfig, or some other method?

Blessed be!

hi pappy_mcfae!

i made an oldconfig. the sensors seem to run. i got an output after running the sensors command:

Code:

I have an ASUS M2NPV-VM motherboard with an AMD X2 3800+ and the IT8716F sensor chip. I get similar messages in the latest kernel, but the sensors appear to work as they did in earlier versions.. I never noticed the messages until I saw snIP3r's post. I think they can be ignored.

That sounds reasonable at the moment since there is nothing proving there's a problem. It's not like I've never ignored mesages. Refcount is 2, should be 1, fixing comes to mind as one that I ignored for quite some time before x.org fixed that.

Blessed be!

hi all!

can someone explain how to use proceed to upgrade to 3.1.0? i think the ebuild is to be put in an OVERLAY directory. but how to apply the patch for sensors-detect?
perhaps someone can help me with this?

the trick is to create a sub-folder called "files" within the lm_sensors-folder, placed in yout overlay-directory. an ebuild lm_sensors-3.1.0.ebuild should do the rest

I've got the same conflict between ACPI and nForce2_smbus in 2.6.33 kernel, and with lm_sensors 3.1.2 installed. I remember back when I installed Gentoo I actually had to run it with the "noacpi" option for it to boot all the way, but now I can drop it and then I get the same warning messages:
Code:
ACPI: I/O resource nForce2_smbus [0x1c40-0x1c7f] conflicts with ACPI region SM00 [0x1c40-0x1c45]
ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver
nForce2_smbus 0000:00:01.1: Error probing SMB2.

I do have a working system, but it doesn't look like the issue has been resolved.
