For quickly reproduce this issue:
1)To Get The Testing Layer:
------------------------
$ git clone git://git.wrs.com/git/projects/wassp-repos/testcases/wrlinux
$ cd wrlinux;git checkout master
2) configure --enable-board=intel-x86-64 --enable-kernel=standard --enable-rootfs=glibc-std --with-layer=$your_clone_path/testcases/wrlinux/wr-testing/bts-dev,wr-dpdk --with-template=feature/bts
3) make fs
4) boot target then run:
# /opt/wr-test/testcases/bts/cpuhotplug_online/runtest.sh
