Oops, yes. There's some recent NUMA breakage - either disable
CONFIG_NUMA, or apply the patches that Andi Kleen just posted on the
mailing list (the second option much preferred, just to verify that
yes, that does fix it).
I was under the impression that NUMA is useful on > 2-way systems only.
Is this true, and if not, under what circumstances is NUMA useful on
2-way Opteron systems?
In other words: why should one want NUMA to be enabled or disabled for
dual Opteron?
Thanks in advance.
