I think the Console messages are trying to say that for "non-programmers" like myself. Note these differences: - Harry has a single CPU; I have 2 CPU. - We both run the same Dell BIOS A07 code. - Harry's Linux kernel is slightly older than my 2.6.35.12-90 Fedora code. - I think we would all agree that Jean's changes do not cause my crash since that code works on Harry's machine but not on mine. Time permitting, I will start doing the research to submit a properly documented bug against Fedora Core 14 regarding this code. I suspect this issue will also reside in FC15 so that is another point to check if time allows. jean raises the real question: does anyone in the Fedora team want to fix this? In closing, I agree with Harry: it is very nice to have some hardware monitoring in a Dell platform. _______________________________________________ lm-sensors mailing list lm-sensors@lm-sensors.org http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
