I have a Toshiba Satellite A305-S6898, and I share the same problem. The problem is that there is no temperature reading for the CPU, that's why it shows 0°C like the original bug reporter says.
After installing lm-sensors, and running 'sensors-detect' the module 'coretemp' was suggested to be loaded. Loading it I now get the following output from 'sensors': $ /usr/bin/sensors acpitz-virtual-0 Adapter: Virtual device temp1: +0.0°C (crit = +92.0°C) coretemp-isa-0000 Adapter: ISA adapter Core 0: +52.0°C (high = +85.0°C, crit = +85.0°C) coretemp-isa-0001 Adapter: ISA adapter Core 1: +51.0°C (high = +85.0°C, crit = +85.0°C) running 'acpi -t': $ /usr/bin/acpi -t Battery 0: Full, 100% Thermal 0: ok, 0.0 degrees C I also tried adding 'acpi_osi="Linux" ' to the kernel options, as this was said to help with this issue, but it does not solve the problem in my case. With no temperature reading, the fan does not work properly. Why is the CPU temperature reading module 'coretemp' not loaded as part of a normal Ubuntu laptop installation? Is it automatically detected and loaded in Jaunty?
