Install perf:
sudo apt-get install linux-tools-common linux-tools-3.11.0-15-generic
(The second package must match your kernel version. You can first install just linux-tools-common and call perf to let it tell you which package it needs.)
Record some 10 seconds of backtraces on all your CPUs:
sudo perf record -g -a sleep 10
Analyse your recording:
sudo perf report
