[gentoo-user] ACPI conflict while loading it87 module

[gentoo-user] ACPI conflict while loading it87 module

[Xi Shen]

hi,


my kernel is 2.6.32-openvz-budarin.1. i emerged the lm_sensors, and
the sensor-dectet tool says i have the it87 sensor. i compiled the
it87 hardware driver as module, and when i try to load it, i got the
following error:

Aug  1 16:56:03 david-gentoo kernel: [  715.671596] it87: Found

Aug  1 16:56:03 david-gentoo kernel: [  715.671669] ACPI: If an ACPI
driver is available for this device, you should use it instead of the
native driver

how to fix this problem?

Use the ACPI module (appropriate for your motherboard) instead of the
it87 module. For example my motherboard (asus P5E64WS) uses the atk0110
(acpi) module... you find it under these conditions (make menuconfig):

Depends on: HWMON [=y] && ACPI [=y] && X86 [=y] && EXPERIMENTAL[=y]
Location:
 -> Device Drivers
 	-> Hardware Monitoring support (HWMON [=y])

I've the same problem and I solved it by adding
acpi_enforce_resources=lax to my kernel parameters in bootloader.
I know that it's not safe way, but it's faster then configure
lm_sensors by hand.

thanks a lot. i am using asus mb, and asus_atk0110 works for me too. :)

I just saw, this weekend in fact, that the newer Phenoms, in fact most
of the recent K10 CPUs, do not work accurately with the atk0110 so when
the driver starts to load, it flatly refuses. I have a 9750 Phenom and
that one works great. Works fine in my X2 4000+. These are all assus
[sic] mobos.  But my 940 Phenom II won't work, thusly:

k10temp 0000:00:18.3: unreliable CPU thermal sensor; monitoring disabled

Isn't k10temp a different/separate module? If I go to lm-sensors site
(http://www.lm-sensors.org/wiki/Devices) I see this:

"k10temp 	 PCI 	 2.6.33 or  standalone driver 	 (2009-12-06) Embedded
sensors are known to be unreliable on the DR-BA, DR-B2, DR-B3, RB-C2 and
HY-D0 revisions of the family 10h CPU, which will never be supported.
Driver contributed by Clemens Ladisch, reviewed by Jean Delvare."

So if you have one of those CPU revisions I guess you're out of luck?
The chipset on my main "rig" (Asus m/b) is running a Intel chipset... I
have only older AMD CPUs (Athlon X2 BE2400) with Gigabyte motherboards
which doesn't have the atk0110 so I'm unfortunately not much of help...

You're right, Peter. I have two M4A79 Deluxe mobos, one with the Deneb
940 and that's where I get the error when I try to use the k10temp
module. The other runs the 9750 Agena and uses the asus_atk0110 module
and works okay. Both are amd64 running 2.6.34. I'll reboot the 940 and
see if that module works.

Well, I added CONFIG_SENSORS_ATK0110=y to my 940/M4A79DX setup and
gkrellm doesn't show anything. That was one test only, so take it with a
grain of salt.
