Hi Jean, > Yes, this is a bug, that will affect almost all users. My bad :( No problem, thanks for confirming it so fast. :-) > Which chip is this? via686a-isa-0c00 (according to sensors). The modules I load are i2c-viapro i2c-isa via686a > Did you run "sensors -s"? Yes. > Does the alarm wear off if you run "sensors" again? No, it stays at this very high RPM value. > You might simply need to set the min RPM count through the > /etc/sensors.conf file and run "sensors -s" afterwards. I have not changed sensors.conf for quite a while and the problems started to appear in 2.9.0. In 2.8.x, everything was fine. I have checked on another system that had the some compile problems I fixed the same way (copying *.h to /usr/local/include/linux). It has w83627hf-isa-0290 as chip and also some weird values: fan1: 5720 RPM (min = 21093 RPM, div = 2) fan2: 0 RPM (min = 84375 RPM, div = 2) What could that be? Maybe I shall erase the sensors.conf and let it re-install it? Thanks Florian
