No, not worse or better, just recently noticable since I just had an unexpected reboot :-). My various linux boxen seem to get this right (or at least more credible numbers), have for years, in the lm_sensors package. This is obviously not a huge problem, but it would be sweet to be able to monitor stuff like system temps reliably & accurately, presumably more so on possibly distant servers. I *think* all this stuff is tied up in the basic system, not pkgs, but I could be wrong. If more info is needed, just ask. Have a good one. -- William A.
