Which version of lm-sensors have you been using for your test? Versions from 2.9.1 to 2.10.4 (inclusive) are annoyingly shifting channel numbers by one for bmc. This doesn't explain everything you observed, but could still have interfered with your diagnostics. So I suggest that you try either lm-sensors SVN (either the stable branch or the upcoming 3.0 version): http://dl.lm-sensors.org/lm-sensors/snapshots/lm-sensors-r4912-20071002.tar.bz2 http://dl.lm-sensors.org/lm-sensors-3/snapshots/lm-sensors-3-r4914-20071002.tar.bz2 -- Jean Delvare
