Thanks! That does appear to work well to get me in un-interrupted. > > I'm suspecting that you have some sort of contest between pm-utils or > similar trying to suspend the laptop, but I'm not certain. > > You should be able to examine the logs and use journalctl to see > precisely what systemd is trying to do at that point. Errr...fraid this is all rather new to me but at the moment I am not getting much of anything out of journalctl.

Done. That seems to work! The laptop isn't sleeping incessantly. :-) So while I was waiting on a response, I copied off the syslog to another box to examine it (in only 3 tries! :-). There is a re-occuring theme and it does look like I may have just missed the info previous to the systemd-sleep. See snippet below. The CTRL-EVENT-SCAN-STARTED /always*/ starts the problem and the nm-dispatcher /always*/ ends. *Where always == every time I have found it in my logs so far. :-) There are usually several seconds between CTRL-EVENT-SCAN-STARTED and whatever happened in the log before it. After this, the pattern is almost identical every time and takes about the same amount of time. sysctl snippet: Oct 23 19:15:37 Senta wpa_supplicant[877]: wlan0: CTRL-EVENT-SCAN-STARTED Oct 23 19:15:38 Senta NetworkManager[582]: <info> sleep requested (sleeping: no enabled: yes) Oct 23 19:15:38 Senta NetworkManager[582]: <info> sleeping...
