Comment 22 for bug 387620

Hi Flavio,
I used the kernel parameter you suggested, and now its allowing me to view
flash heavy sites for a bit longer. But it still shuts down after 10 mins. I
can hear the fan really loud on sites like youtube.
I installed lmsensors,and through the applet on the panel I can see the
temperature rise to ~79 C while viewing youtube. and then it goes to
80...and then later initiates a shutdown !!!
I tried throttlling the cpu with the cpu scaling applet, but even
this doesn't help. May be I should open up the laptop and clean it out. Dust
on the fan is one issue i read about.

Thanks for the help!
