Comment # 3 on bug 878720 from Stanislav Brabec

It looks like that during /usr/lib/pm-utils/sleep.d/50rcnetwork resume quirk,
10 seconds after first resume, the new suspend was initiated.

Maybe both pm-utils and systemd initiated suspend independently.

Could you reproduce in 13.2 or Tumbleweed/Factory?

Do you have suspend package installed?

Will it help if you remove suspend package?

Will it help if you remove both suspend and pm-utils package?
