Thanks Martin, I'll take a look. One thing I have noticed on B0 numa_sched:
I added node load to /proc/stat and see a problem. look at procs_running
compared to the total of node1..4. They do not agree. It looks as if the
node load and runqueue lengths may have gotten out of sync. I could not
find any obvious place this happened.
