"command response could not be provided"

[Rob Munsch]

I've gotten the IPMI drivers, ipmitool, and assorted other goodies all 
working on a Poweredge 1750, but half the sensors come up with (very 
verbose) errors, thusly:

-----
~# ipmitool sdr
Basebrd Mgt Ctlr | Static MC @ 20h   | ok
Error reading sensor CPU 1 (#01): Command response could not be provided
Error reading sensor CPU 2 (#02): Command response could not be provided
Error reading sensor CPU 3 (#03): Command response could not be provided
Error reading sensor CPU 4 (#04): Command response could not be provided
CPU Planar       | 32 degrees C      | ok
Ambient          | 19 degrees C      | ok
CPU              | 1.51 Volts        | ok
-----

Is this a problem with the BMC itself, does it mean those sensors aren't 
present, did i not do this right, all three, or something else..?
