I looked in the supermicro bios. Sadly there are no options there for diabling a CPU. All you can do is disable CPU cores but from the looks of it you need a minimum of 1 available for a CPU. I will investigate that furhter and play with it.</div>

Have you tried disabling the second CPU in the BIOS? You say you have <br>
played with NUMA in the BIOS, but how about ruling it out completely by <br>
going to a single CPU?<br>
