Well, everything that could be causing load is certainly off.

It isnt possible that the dell_rbu kernel module would be causing *any*
load. (the module is open source, take a look for yourself.) It doesnt
do *any* processing of anything unless you are actually running a BIOS
update. You should look at other things. What else is running? What does
top say is causing the load?

You sure it isnt some random system daemon? You havent provided any data
to show what is causing the cpu load.
