If I let it run for 3-5 minutes load average increases over 5 and the temperature goes from a typical 50C to 78C. Sometimes then the laptop shuts down. Version-Release number of selected component (if applicable): kernel - 2.6.23.9-85.fc8 How reproducible: Always Steps to Reproduce: 1. Use Firefox to go to a page that uses flash, such as YouTube. 2. Play video or just browse for a while. 3. CPU load average increase to the point that everything freezes. Actual Results: Expected Results: Additional info:
npviewer.bin is part of nspluginwrapper.
Do you have a dual core laptop by chance? Flash on some web pages easily use 100% of both cores in NORMAL OPERATION. This does tend to make things very hot, and some machines without enough cooling capacity can kill themselves. By the very fact that high load alone can overheat your laptop, this isn't any particular software's fault, but rather your cooling capacity. http://www.amazon.com/Cooler-Master-NotePal-Laptop-R9-NBC-ADAS/dp/B0009WPSEC There is a reason why products like this are sold. (I don't know about the effectiveness of this particular model. I don't own one.) This is not a bug in firefox or nspluginwrapper. It is possible that the Flash plugin is working harder than it needs to due to not making full use of available CPU/GPU optimizations, but if that is the case (I don't know) then it is Adobe's problem. Sorry.
Thank you very much. I understand there is a cooling problem with my laptop, however I've seen the load average go up to 20 if npviewer runs for 10 minutes so it's not just a spike. Everything freezes up, the mouse does not move, etc. I don't think that's reasonable even if flash is process intensive.
