With Debian Sid/unstable with Linux 4.9.18 suspend and resume times are
benchmarked with pm-graph [1], and the command below.

```
sudo ./analyze_suspend.py -config config/suspend-callgraph.cfg -filter rade=

It turns out that with 700 ms the radeon module takes the majority of the t=

during resume.
