Dear all,
I just put together a new PC with the following components:
mainboard: Gigabyte GA-A75M-UD2H, newest BIOS (beta)
CPU: AMD A8-3850 APU
Using lm_sensors, one temperature of the APU via it87 is shown far too high. The BIOS/PC Health Status (after reboot) reports basically 34°C and 34°C which were also the usual temparatures at my old PC when just surfing or doing some office stuff. But for teh new PC lm_sensors shows now for the CPU a temperature of 59°C which is about the sum of the first temperature and the temperature in the case/housing (case has an own thermocouple). It is the same behaviour with the kernel module as well as the driver from your download page.
I would be happy if you could investigate a bit further to get also a correct temperature reading.
Thanks,
Klaus
Here some further details:
mb40 etc # uname -a
Linux mb40 3.4.9-gentoo #4 SMP Sun Sep 30 16:57:03 CEST 2012 x86_64 AMD A8-3850 APU with Radeon(tm) HD Graphics AuthenticAMD GNU/Linux
Here is the relevant output of 'sensor-detect':
Do you want to probe the I2C/SMBus adapters now? (YES/no):
Using driver `i2c-piix4' for device 0000:00:14.0: AMD Hudson-2 SMBus
Next adapter: SMBus PIIX4 adapter at 0b00 (i2c-0)
Do you want to scan it? (yes/NO/selectively): yes
Client found at address 0x52
Probing for `Analog Devices ADM1033'... No
Probing for `Analog Devices ADM1034'... No
Probing for `SPD EEPROM'... Yes
(confidence 8, not a hardware monitoring chip)
Client found at address 0x53
Probing for `Analog Devices ADM1033'... No
Probing for `Analog Devices ADM1034'... No
Probing for `SPD EEPROM'... Yes
(confidence 8, not a hardware monitoring chip)
Now follows a summary of the probes I have just done.
Just press ENTER to continue:
Driver `it87':
* ISA bus, address 0x228
Chip `ITE IT8720F Super IO Sensors' (confidence: 9)
Driver `k10temp' (autoloaded):
* Chip `AMD Family 12h and 14h thermal sensors' (confidence: 9)
sensor3.conf for it87 is
chip "it87-*" "it8712-*" "it8716-*" "it8718-*" "it8720-*"
set temp1_type 4
set temp2_type 4
