Could well be that I misunderstand > that... I'm sorry for the noise about a seemingly well known problem. (My previous hardware also was a Thinkpad L14 and that worked out of the box for some years, so I thought I hit some new problem. And when I tried the powersave governor that let the system heat raise to death while the fan speed remained at 3000 RPM I got really confused.) I digged some more, found *thinkfan* and currently, webkit-gtk is being built with performance profile at around (hopefully safe) 84=E2=84=83. Regards, Dirk
