Install perf:
```
sudo apt-get install linux-tools-common linux-tools-generic linux-tools-3.13.0-35-generic
```
(The second package must match your kernel version. (Find with: uname -a) You can also just first install linux-tools-common and linux-tools-generic

then type “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:
```
perf report
```
