I got this hammered again manually this morning by just running the cpuset_hotplug test with ltp
$ cat /home/ubuntu/short
cpuset_hotplug cpuset_hotplug_test.sh
$ sudo /opt/ltp/runltp -f /home/ubuntu/short ; sudo reboot

* with -1160 the fail rate is 5 out of 25 attempts
* with -1159 deb downloaded from the link you provided, the fail rate is 2 out of 25 attempts
* with -1158 the fail rate is 4 out of 25 attempts

I am not sure why this seems failing constantly when being tested on our jenkins. Probably because of other tests started before this cpuset_hotplug test.
