I am happy to report success. First off I would like to thank everyone that helped. I am using kernel 2.6.21 with the ipmi experimental patch from http://bmcsensors-26.sourceforge.net/. The main issue was loading the right modules in the right order. Here is what I loading in /etc/rc.local: ######################################################################### # I2C adapter drivers modprobe i2c-piix4 modprobe eeprom modprobe ipmp_si modprobe ipmi_msghandler modprobe ipmisensors # sleep 2 # optional /usr/bin/sensors -s # recommended ########################################################################## Here is the output of sensors: romberg at smaug > sensors bmc-isa-0000 Adapter: ISA adapter in1: +0.39 V (min = +1.43 V, max = +1.87 V) in2: +2.23 V (min = +2.54 V, max = +3.45 V) in3: +2.23 V (min = -13.81 V, max = -10.21 V) in4: -1.64 V (min = +10.21 V, max = +13.80 V) in5: +3.53 V (min = +4.26 V, max = +5.75 V) in6: +4.99 V (min = +2.77 V, max = +3.78 V) in7: +3.72 V (min = +2.80 V, max = +3.79 V) in8: +2.96 V (min = +2.14 V, max = +3.15 V) in9: +3.74 V (min = +1.07 V, max = +1.43 V) fan1: 0 RPM (min = 1920 RPM) fan2: 3840 RPM (min = 1920 RPM) fan3: 3750 RPM (min = 1830 RPM) fan4: 3600 RPM (min = 1830 RPM) fan5: 4200 RPM (min = 1830 RPM) fan6: 4200 RPM (min = 1830 RPM) temp1: -12.8?C (high = +5?C, hyst = -13?C) temp2: +138.0?C (high = +8?C, hyst = +0?C) temp3: +41.0?C (high = +8?C, hyst = +0?C) temp4: +39.0?C (high = +8?C, hyst = +0?C) temp5: +39.0?C (high = +8?C, hyst = +0?C) temp6: +40.0?C (high = +4?C, hyst = +0?C) temp7: +27.0?C (high = +5?C, hyst = +0?C) The voltages look fine or I do not see anything too out of the norm. fan1's rpms for some reason is not reported. The fan is spinning fine and no fan faults are reported on the case status panel. For temp1 and temp2, I have no idea what they are. The CPUs are temp3 through temp6. I am guessing temp7 is a hard drive. The system has a Dell PERC 3DC raid controller with a single 108GB raid5 array. Overall I am happy that I can at least now monitor the CPU temps. Now I just need to find a nice graphical client since xsensors does not work with BMC based systems. Keith
