I am suppressed that your desktop shows any symptoms on rt21. I tried my
smaller AMD box (A10), an Intel two sockets and a four socket box. Each
of them was fine with the run.sh and manual futex_wait invocation.
Could you please send the config of your desktop box?

(sent offline)

btw: I tried booting the two and four sockets box with less memory so
that the box is using just one memory node but nothing changed. Let me
try with the config of yours.

BTW back, I reran virgin 4.9-rt21 on desktop box while off doing the
have something resembling a life thing, and it did not stall in 50
iterations of performance/run.sh (bloody fickle thing).  Hohum, take it
for whatever you think it's worth.
