I hate to crap on this wonderful parade, but on my T60 (i386, dmesg at bottom) running 25 march snap the heat has bumped a full 10DegC from what was "normal" before. I'm sorry for the lack of science here and I have no hard numbers w/wo patch yet but in the past my steady state on this machine w/o firefox was something like 70DegC, w/just some xterms and emacs (aka life). Starting firefox generally added 10DegC before I did anything at all and I always had to watch the heat and kill firefox when we crossed 95DegC or Bad Things Happened; thus I live with w3m in one hand and treat firefox as some kind of luxury... tor-browser was, strangely, less hard on things but maybe that's just because I never have too many tabs there (also, maybe firefox-esr is a little lighter, not sure). Now it will be a challenge to see if I can cvs up, back out the patch and build a kernel without ringing the bell (100DegC). I freely admit this is an old, P.O.S. laptop and that there might be some HW issue (fan seems fine but I haven't taken it apart and really looked). It does seem like the difference in the scheduler has a remarkable effect on heat in my case. Does anyone else see this? > It's not just "the videos in Firefox" - everything works *so* much more > fluently with the patch there's no way I would go back living without it. It never occurs to me to try watching videos in firefox.
