Hi Jean, Please go here: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=249428 For the full story. I think this is caused by this patch: http://lists.lm-sensors.org/pipermail/lm-sensors/2007-March/019227.html Where you not only converted it to a platform driver but also made the detection more stringent (shouldn't that have been a seperate patch?). I'll be working with the reporter to see whats up, but since you are the expert your input would be valued very much. I think the easiest would be if you could join the discussion in Fedora's bugzilla. Setting up an account is a breeze. Thanks & Regards, Hans
