Subject: bad temperature values from w83781d in 2.6.22
Hi,
after upgrading from 2.6.21 to 2.6.22 the CPU temperatures shown by
w83781d look unreal. They were in a range from 40°C when idle to
75°C under full load with 2.6.21. The values shown now are in a very
small range from 77°C to 82°C. From the (low) noise of the fan I can
tell that the temperature is <50°C.
The third temperature shown is completely wrong.
I have a Tyan Tiger MPX board with a w83782d chip. Output from
"sensors":
w83782d-i2c-0-2d
Adapter: SMBus AMD768 adapter at 80e0
+5 V: +4.81 V (min = +4.76 V, max = +5.24 V)
3 VSB: +3.30 V (min = +2.85 V, max = +3.15 V) ALARM
chs3 Fan: 2122 RPM (min = 2657 RPM, div = 4) ALARM
VRM2 Temp: -208°C (high = -176°C, hyst = -181°C) sensor = transistor
CPU1 Temp: +78.5°C (high = +80°C, hyst = +75°C) sensor = transistor ALARM
CPU2 Temp: +77.5°C (high = +80°C, hyst = +75°C) sensor = transistor ALARM
alarms:
beep_enable:
Sound alarm enabled
# cat /sys/bus/i2c/devices/0-002d/temp*_input
-209000
77500
77500
Any ideas?
