Description Forgotten User K-uAvjqJ3n 2009-09-15 13:14:49 UTC

When temperature reaches 98-99 degrees C kernel logging starts spewing
[51150.684953] CPU0: Temperature above threshold, cpu clock throttled (total events = 463537)
[51150.686263] CPU0: Temperature/speed normal
[51150.687491] CPU0: Temperature above threshold, cpu clock throttled (total events = 463538)
[51150.688797] CPU0: Temperature/speed normal
[51150.689555] CPU0: Temperature above threshold, cpu clock throttled (total events = 463539)
[51150.690865] CPU0: Temperature/speed normal


about 20 times a second.

while I appreciate the notification it is eating my harddisk quite rapidly and I assume is slowing my system

This is fixed in latest 11.2 GM.
If this is a workstation you might want to consider adding a more powerful CPU fan, if it's a laptop, try to clean the fan with a vacuum cleaner when the machine is switched off.
