[SOLVED] Missing acpi hwmon sysfs interface on Eeepc 1000H

Hi,
I am running a fresh install using Linux 3.15.8-1-ARCH kernel on Asus Eeepc 1000H and there is a problem with the detected thermal sensors.
After configuring sensors using sensors-detect (yes to all answers, full detection), I only get this:
$ sensors
coretemp-isa-0000
Adapter: ISA adapter
Core 0:        +4.0°C  (crit = +90.0°C)

eeepc-isa-0000
Adapter: ISA adapter
fan1:         970 RPM

It misses the acpitz-virtual-0 corresponding to the acpi thermal zone which temperature can be read in /sys/class/thermal/thermal_zone0/temp and with "acpi -t" command.

Unfortunately, the temperature reported by coretemp-isa-0000 sensor is wildly wrong, and cannot be used to drive fancontrol, whereas the acpi temperature is correct.

I checked that hwmon, thermal_sys, coretemp and eeepc_laptop modules are loaded.
I also tried to add /etc/sensors.d/EeePC-0123456789 as said in https://forums.archlinux.fr/topic14506.html (french):
chip "acpitz-virtual-0"
  label temp1 "temp1"
  compute temp1 @-20,@-20

  label temp2 "Core 0"
  compute temp2 @-20,@-20

but I am not able to get the desired output of sensors -u. all I get is that:
$ sensors -u
coretemp-isa-0000
Adapter: ISA adapter
Core 0:
  temp2_input: 2.000
  temp2_crit: 90.000
  temp2_crit_alarm: 0.000

eeepc-isa-0000
Adapter: ISA adapter
fan1:
  fan1_input: 980.000

I also tried to install acpi-eeepc-generic from AUR, but unsurprisingly, it did not change anything.
All I can tell about former behaviour is that I had no problem running sensors and using fancontrol with Xubuntu 12.04 which uses 3.2.0 kernel.

Can someone give me a clue of what is going on here about missing acpitz-virtual-0 sensor ?


Best regards,

The computer is now broken, so marking thread as solved even if the issue has not been really solved.
