Description: Ubuntu 8.04.1
Release: 8.04
uname -a:
2.6.24-19-generic #1 SMP Fri Jul 11 23:41:49 UTC 2008 i686 GNU/Linux

analyzing CPU 0:
driver: acpi-cpufreq
CPUs which need to switch frequency at the same time: 0
hardware limits: 600 MHz - 1.80 GHz
available frequency steps: 1.80 GHz, 1.60 GHz, 1.40 GHz, 1.20 GHz, 1000 MHz,
800 MHz, 600 MHz
available cpufreq governors: userspace, powersave, ondemand, conservative,
performance
current policy: frequency should be within 1.80 GHz and 1.80 GHz.
The governor "performance" may decide which speed to use
within this range.
current CPU frequency is 1.80 GHz.
3. When viewing multiple flash sites Firefox uses 100% cpu and the cpu
temperature raises to 65˚C. One would expect that some programm (like acpi)
would manage cpu fan speed and tell the fan to turn faster on high temperature.
4. Instead the cpu fan turns with constant rpms no matter how high the cpu
temperature. On some point the system freezes and hard reboot is needed. The
only thing that somehow manages the temperature seems to be cpufreqd witch,
when cpu temperature goes to ~60˚C, drops the frequency to 1.40 GHz.
