JF, don't drop CC'ed people please. Once you've started test.sh and it
hanged you were to "cat /sys/kernel/debug/tracing/trace" and provide
us output. Thanks for smaps.log it has shown that there is no special
IO zones in memory. Thus please run test.sh again and show us
"cat /sys/kernel/debug/tracing/trace".
