From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.1) Gecko/20031114 Galeon/1.3.10 Description of problem: Since installing the 2.4.22-1.2129.nptl kernel update, my Sony VAIO laptop has shutdown twice apparently due to overheating. Further experimentation showed that the 2.4.22-1.2115.nptl kernel did correctly activate the CPU fan when required, and the 2.4.22-1.2129.nptl kernel does not. The laptop concerned is a PCG-Z600LEK with a 700MHz Pentium III with SpeedStep. The problems only started occuring after the kernel update. Version-Release number of selected component (if applicable): 2.4.22-1.2129.nptl How reproducible: Always Steps to Reproduce: Turn on laptop - it will cut out after approx 1 hour (depending on temperature). Actual Results: Shutdown probably due to overheat. Expected Results: Remains operating normally, using cooling fan as necessary. Additional info:
