Hi,
May 6 09:20:52 pvr1 kernel: [ 71.081080] Critical temperature
reached
(127 C), shutting down.
127 C seems also unreal to me, I guess it wouldn't survive such temp.
I suggest checking the BIOS (PC-Health) readings, these values should
be correct. If you have acpi_enforce_resources=lax kernel boot param,
please remove it. And also try to boot the F15 (e.g. from liveCD) :)
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.
AFAIK under /sys/class/hwmon/hwmon* you can set several parameters:
temp[1-*]_type Sensor type selection,
temp[1-*]_offset Temperature offset which is added to the temperature
reading
More info in: /usr/share/doc/kernel*/Documentation/hwmon/sysfs-interface
In case it is it87 bug, please report it to kernel
