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

[Wolfgang Kufner]

I have stressed the cpu with two instances of:
cat /dev/zero > /dev/null

and logged this till forced shutdown (the stressing begins later than the log):
watch -n 1 "date>>temperature;grep . /proc/acpi/thermal_zone/TZS0/temperature>>temperature;grep . /proc/acpi/thermal_zone/TZS1/temperature>>temperature;grep . /sys/devices/system/cpu/cpu*/cpufreq/*>>temperature;dmesg |grep ACPI>>temperature"

The last log entry shows frequency being reduced to minimum, but by that time it is too late:
scaling_cur_freq:1000000
scaling_max_freq:1299600
