Got scientific updated and running on 3.3.8 pre-emptive, although it’s bloated at present like the stock kernel.  The kernels I had built for CentOS were missing things needed by scientific, well at least it thinks it needs them, start up scripts try to load modules we really have no need for in our environment.  So running a 3.3.8 kernel that is pretty much configured like the stock 2.2.26 kernel for now which is inefficient but better than the original.  I’ll lean it out as time allows but for now bigger fish to fry.
