With a max-depth of 10 it’s too large, and even with 16 GB memory the browser
takes ages to render it. I can try to trim the trace file. It should be
possible to filter stuff, but I haven’t figured out how to pass the device.
Though, you can easily try it yourself.
```
$ git clone <a href="https://github.com/01org/pm-graph">https://github.com/01org/pm-graph</a>
$ cd pm-graph
$ vim config/suspend-callgraph.cfg # change maxdepth to 10
$ sudo ./sleepgraph.py -config config/suspend-callgraph.py
# wait
$ ls -ltr # shows you the output directory
```
It normally easier to look at the trace file directly.

I’ll try.</pre>
