[Bug 563815] Re: [STAGING] Critical temperature reached (100 C), shutting down. throttling too little, too late.

[Wolfgang Kufner]

** Description changed:

+ [Workaround]
+ As a workaround the maximum cpu frequency can be limited:
+ as root: echo 1333000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq; echo 1333000 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq
+ to check the current maximum frequency:
+ grep . /sys/devices/system/cpu/cpu*/cpufreq/scaling_max_freq
+ 
+ [Report]
  Under heavy use the Acer Extensa 5630Z always overheats and shuts down. I noticed this in lucid, but karmic shows the same principal problem.
- The main culprit seems to be that the clock frequency is reduced too little and too late. 
+ The main culprit seems to be that the clock frequency is reduced too little and too late.
  It should reduce clock frequency more/sooner to avoid the forced shutdowns.
