AMD A10 Temps Reporting Incorrect

I just did a new build with one of AMD's A10 APUs. All is running great with the exception of lm_sensors reporting completely incorrect temperatures. sensors output:

k10temp-pci-00c3
Adapter: PCI adapter
temp1:         +1.0 C  (high = +70.0 C)
                       (crit = +80.0 C, hyst = +79.0 C)

it8728-isa-0228
Adapter: ISA adapter
in0:          +1.31 V  (min =  +0.00 V, max =  +3.06 V)
in1:          +1.50 V  (min =  +0.00 V, max =  +3.06 V)
in2:          +2.00 V  (min =  +0.00 V, max =  +3.06 V)
in3:          +2.04 V  (min =  +0.00 V, max =  +3.06 V)
in4:          +2.06 V  (min =  +0.00 V, max =  +3.06 V)
in5:          +2.23 V  (min =  +0.00 V, max =  +3.06 V)
in6:          +2.22 V  (min =  +0.00 V, max =  +3.06 V)
3VSB:         +3.36 V  (min =  +0.00 V, max =  +6.12 V)
Vbat:         +3.07 V  
fan1:        1569 RPM  (min =    0 RPM)
fan2:           0 RPM  (min =    0 RPM)
fan3:        1464 RPM  (min =    0 RPM)
fan4:        1530 RPM  (min =    0 RPM)
fan5:           0 RPM  (min =    0 RPM)
temp1:        +26.0 C  (low  = +127.0 C, high = +127.0 C)  sensor = thermistor
temp2:         -8.0 C  (low  = +127.0 C, high = +127.0 C)  sensor = thermistor
temp3:        +17.0 C  (low  = +127.0 C, high = +127.0 C)  sensor = disabled
intrusion0:  ALARM

My BIOS reports more realistic remperatures, 40-45C for the CPU and ~25C for motherboard. Any idea on what I can do to get correct readings?

Re: AMD A10 Temps Reporting Incorrect

I have the same problem on my AMD A4 socket FM1. It's never bothered me that much, but it is annoying. Could it be a bug with the k10temp and it87 modules?

Re: AMD A10 Temps Reporting Incorrect

Slight update: the inxi command appears to report the correct temperature

Sensors:  System Temperatures: cpu: 26.0C mobo: N/A p

Why is there the discrepancy?

Re: AMD A10 Temps Reporting Incorrect

Here's my sensors output:

k10temp-pci-00c3
Adapter: PCI adapter
temp1:        +18.5°C  (high = +70.0°C)

it8720-isa-0228
Adapter: ISA adapter
in0:          +1.01 V  (min =  +0.00 V, max =  +4.08 V)
in1:          +1.50 V  (min =  +0.00 V, max =  +4.08 V)
in2:          +3.36 V  (min =  +0.00 V, max =  +4.08 V)
+5V:          +2.96 V  (min =  +0.00 V, max =  +4.08 V)
in4:          +3.04 V  (min =  +0.00 V, max =  +4.08 V)
in5:          +2.14 V  (min =  +0.00 V, max =  +4.08 V)
in6:          +2.14 V  (min =  +0.00 V, max =  +4.08 V)
5VSB:         +2.98 V  (min =  +0.00 V, max =  +4.08 V)
Vbat:         +3.33 V  
fan1:        1630 RPM  (min =   10 RPM)
fan2:           0 RPM  (min =    0 RPM)
fan3:           0 RPM  (min =    0 RPM)
temp1:        +39.0°C  (low  = +127.0°C, high = +127.0°C)  sensor = thermistor
temp2:        +87.0°C  (low  = +127.0°C, high = +127.0°C)  sensor = thermistor
temp3:        +28.0°C  (low  = +127.0°C, high = +70.0°C)  sensor = thermistor
intrusion0:  ALARM

and inxi:

Sensors:   System Temperatures: cpu: 39.0C mobo: 87.0C

so inxi takes temp1 as cpu and temp2 as a motherboard reading.
I guess temp1 could be the cpu, but what is k10temp picking up then? temp2 is always at 87, so I think that's incorrect, much like your temp2 reading.
