It prints out a bunch of stuff, but the word SRAT wasn't in the
output.

I don't remember a node interleaving in the BIOS -- There's a ECC mode,
where I only get 4/6 slots for usable memory, or an optimized mode that uses
6/6 mem sort.  Each processer has it's own set of 6-slots for memory
(PowerEdge 610 dual X5660's)...

I wonder if the optimizing mode is node interleaving?   But the only other
result results in taking a 1/3rd memory penalty...Hmm...

I'm wondering about this BIOS .. I had to use pcie_aspm=force to get it
to get some parts to work at all.  Like the on-board I/O DMA engine --
linux didn't even see the hardware without the aspm=force.

Maybe a bios update is needed?  will probe along those lines...

I can always call Dell tech support...still under warantee...;-)

Thanks for the ideas and confirmation....
