With Debian Sid/unstable with Linux 4.9.25 suspend and resume times are
benchmarked with pm-graph [1], and the command below.

```
sudo ./analyze_suspend.py -config config/suspend-callgraph.cfg
```

It turns out that with 258 ms the radeon module takes the majority of the t=
ime
during suspend.

In that cycle one `radeon_bo_evict_vram` call takes the longest with 198 ms.
