Ubuntu – Can’t get the right CPUcore temperature (Acpi chip)


After replacing my motherboard I try to get Psensor working correctly but still I cannot get the right temperature for my CPUcore temp, it's always -127C degrees. I installed lm-sensors and everything it's needed to check the temp, so after running:

sudo sensors-detect

I answered yes to everything and it found:

Driver `f71882fg':
* ISA bus, address 0x295
Chip `Fintek F71882FG/F71883FG Super IO Sensors' (confidence: 9)

I ran:

sudo service kmod start

when I do:

sudo modprobe f71882fg

I get:

modprobe: ERROR: could not insert 'f71882fg': Device or resource busy

the output of dmesg | tail says:

[47593.565779] f71882fg: Found f71882fg chip at 0x290, revision 32
[47593.565857] ACPI Warning: SystemIO range 0x00000290-0x00000297 conflicts with OpRegion 0x00000295-0x00000296 (\IP__) (20140424/utaddress-258)
[47593.565870] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver

What would be my further actions?

  • As Oli says, you only need the coretemp module to read Intel CPU core temperature.

    I have a similar problem with my w83667hg hardware monitor driver. The workaround is to add acpi_enforce_resources=lax to the kernel command line. To that end

    1. edit /etc/default/grub and insert acpi_enforce_resources=lax into the parameter string of GRUB_CMDLINE_LINUX, e. g.

    2. then run update-grub and reboot.
