Regretfully initiating suspend via:
sudo sh -c sync echo 1 /sys/power/pm_trace pm-suspend
... does not suspend the computer, it seems to wake up immediately.
Suspending the computer via Gnome plugin or closing the lid results in a
failed suspend.

I've done some tests:
- it doesn't matter which port I plug in the mobile wifi - suspend will fail
- if the mobile wifi is turned off, suspend works fine (no suprise here)
- plugging in my usb stick, doesn't have a negative effect
- plugging in my external hard drive, doesn't have a negative
