** 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.
