thermal shutdown is there any control for how the kernel reads tempurature
by Alan Anderson 15 May '11

15 May '11

Hi Perhaps this is the wrong list, but it is the best match I saw. If there is a better list let me know. New ECS A790GXM motherboard intended to be a new Mythtv backend. Fresh fedora core 14 install. Right after the install on the first login the system shut down before I could type in the password. In dmesg I see the following: May 6 09:20:52 pvr1 kernel: [ 71.081080] Critical temperature reached (127 C), shutting down. I installed the lm_sensors rpm and see the following on a boot after 10 hours powered off sitting at room temperature. [root@pvr1 ~]# uptime 08:29:07 up 0 min, 1 user, load average: 1.45, 0.45, 0.16 [root@pvr1 ~]# service lm_sensors status acpitz-virtual-0 Adapter: Virtual device temp1: +30.0°C (crit = +110.0°C) k10temp-pci-00c3 Adapter: PCI adapter temp1: +11.0°C (high = +70.0°C) it8716-isa-0e80 Adapter: ISA adapter in0: +1.04 V (min = +0.00 V, max = +4.08 V) ALARM in1: +2.14 V (min = +0.00 V, max = +4.08 V) ALARM in2: +1.55 V (min = +0.00 V, max = +4.08 V) ALARM in3: +2.99 V (min = +0.00 V, max = +4.08 V) ALARM in4: +1.22 V (min = +0.00 V, max = +4.08 V) ALARM in5: +2.48 V (min = +0.00 V, max = +4.08 V) ALARM in6: +2.50 V (min = +0.00 V, max = +4.08 V) ALARM in7: +3.30 V (min = +0.00 V, max = +4.08 V) ALARM Vbat: +3.04 V fan1: 1885 RPM (min = 0 RPM) fan2: 0 RPM (min = 0 RPM) fan3: 0 RPM (min = 0 RPM) temp1: +18.0°C (low = +127.0°C, high = -53.0°C) ALARM sensor = thermal diode temp2: +23.0°C (low = -1.0°C, high = +127.0°C) sensor = thermistor temp3: +111.0°C (low = -1.0°C, high = +127.0°C) sensor = thermal diode <-- I do not know if this is a motherboard issue or the kernel is reading the thermal diode wrong but jumping from room temp to 111C on a cold boot is a little hard to believe. the CPU is only at 23C. Six minutes after boot its up to 120C. [root@pvr1 ~]# uptime 08:34:44 up 6 min, 1 user, load average: 0.01, 0.15, 0.11 [root@pvr1 ~]# service lm_sensors status acpitz-virtual-0 Adapter: Virtual device temp1: +30.0°C (crit = +110.0°C) k10temp-pci-00c3 Adapter: PCI adapter temp1: +12.5°C (high = +70.0°C) it8716-isa-0e80 Adapter: ISA adapter in0: +1.04 V (min = +0.00 V, max = +4.08 V) in1: +2.14 V (min = +0.00 V, max = +4.08 V) in2: +1.55 V (min = +0.00 V, max = +4.08 V) in3: +2.99 V (min = +0.00 V, max = +4.08 V) in4: +1.22 V (min = +0.00 V, max = +4.08 V) in5: +2.48 V (min = +0.00 V, max = +4.08 V) in6: +2.50 V (min = +0.00 V, max = +4.08 V) in7: +3.30 V (min = +0.00 V, max = +4.08 V) Vbat: +3.04 V fan1: 1849 RPM (min = 0 RPM) fan2: 0 RPM (min = 0 RPM) fan3: 0 RPM (min = 0 RPM) temp1: +19.0°C (low = +127.0°C, high = -53.0°C) ALARM sensor = thermal diode temp2: +29.0°C (low = -1.0°C, high = +127.0°C) sensor = thermistor temp3: +120.0°C (low = -1.0°C, high = +127.0°C) sensor = thermal diode Is there any control in the kernel to pass some sort of offset or scaling value to what ever is reading the thermal diode? This thing has got to be reading 3-4 times the actual temp. Thanks in advance for any ideas Alan Anderson
