AMD Phenon II k10temp no temp or fan sensors reading

For some reason sensors always read my cpu temp = 0.

# sensors
k10temp-pci-00c3
Adapter: PCI adapter
temp1:         +0.0°C  (high = +70.0°C)

radeon-pci-0100
Adapter: PCI adapter
temp1:        +69.5°C  (crit = +120.0°C, hyst = +90.0°C)

# cat /etc/conf.d/lm_sensors 
# Generated by sensors-detect on Tue Jul 15 15:32:43 2014
# This file is sourced by /etc/init.d/lm_sensors and defines the modules to
# be loaded/unloaded.
#
# The format of this file is a shell script that simply defines variables:
# HWMON_MODULES for hardware monitoring driver modules, and optionally
# BUS_MODULES for any required bus driver module (for example for I2C or SPI).

HWMON_MODULES="f71882fg"

dmesg:
[  413.344029] f71882fg: Found f71889fg chip at 0x600, revision 21
[  413.344055] ACPI Warning: SystemIO range 0x0000000000000600-0x0000000000000607 conflicts with OpRegion 0x0000000000000605-0x0000000000000606 (\HMOR) (20140214/utaddress-258)
[  413.344061] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver

I did sensors-detect several times but it does not help. I know that k10temp is problematic in general but usualy it provides some temp information. What is more I do not get any information on fans' speed.
My CPU: AMD Phenom(tm) II X6 1100T
Motherboard: MSI 790fx-gd70
Kernel: 3.15.5-1-ARCH

Please help :-)

Re: AMD Phenon II k10temp no temp or fan sensors reading

acpi_enforce_resources=lax should enable access to the f71889fg with its thermal sensors and fan controllers.

I don't know what's wrong with k10temp, I've never seen it fail like that.

Re: AMD Phenon II k10temp no temp or fan sensors reading

Thank you! It helps with f71889fg.
I still don't know why k10temp does not work but it is less important for me now.
