I don't know if a me-too may help you, but I have exactly the same
trouble on a whole set of dell servers, all with bmx drivers (suse 10.1
kernel) and values fetched by an homebrew daemon and collected via rrd.

on my side measures are performed on a 10sec frequency basis

almost once a day per machine.

I can patch my app in order to give you those exact numbers (I'm afraid
