Comment 23 for bug 1487919

The difference under systemd is indeed mostly that the pm-utils suspend quirks are not being run any more, like /usr/lib/pm-utils/sleep.d/60_wpa_supplicant . Does it help if you run

  sudo wpa_cli suspend

then suspend, resume, and run

  sudo wpa_cli resume

? If so, then we need to teach the wpasupplicant package to do that. This part is most likely a duplicate of bug 1422143 then.

However (1) wpasupplicant certainly shouldn't segfault, and (2) things like touchpad still being active during suspend is a kernel issue, so this report is still legit (but should be kept for those issues, and the wpasupplicant one should become separate).
