4 years ago Further to this, my systemd sleep.conf is just all the defaults, as shipped, but I may play around with it to see if I get any different behaviour or clues:

apt policy $PACKAGE NAME): N/AIssue/Bug Description: When taking laptop out of suspend (eg. opening lid if it was suspended while closed, or waking up with the power button if I manually suspended), the system will sometimes freeze.
I see the last few messages on the console (usually some wifi adaptor warnings), but other than that it is a full system freeze - capslock keys won't toggle, and the normally-blinking _ cursor is frozen. I have included some syslog clues at the end of the report. I'm not yet sure whether it's a case of freezing while attempting to wake up, or something going wrong when it is suspending. The logs do seem to indicate that in the failures, the suspension never really completes properly (although it's hard to tell with this sort of issue because some log writing is obviously paused, waiting to be written once the system is woken up)
I've seen similar reports for other Thinkpads or Lenovos but I thought I'd try to share some more info and logs here about my specific issue.
Steps to reproduce (if you know): Suspend the Thinkpad with the suspend menu option or by closing the lid and waiting for the configured sleep time. Wake the Thinkpad either by opening the lid if closed, or with a tap on the power button if already open.
Expected behavior: The system wakes up and the gnome session is resumed
Other Notes: I have copied in some snippets from syslog with some inline comments. Apologies if it is an annoyingly long paste. Happy to investigate further logs or look into system-sleep or system-suspend debugging if that will help
This first log snippet shows an example of the freezing / failing suspend. Log begins just as I have clicked the suspend button
Here, presumably, is the crash. Nothing appears to have been logged when I pressed the button (though I do at least see the display wake up to show a TTY with some wifi log messages). And indeed, the systemd-sleep process doesn't appear to have actually ended? Or at least didn't get logged as such. As below, you can see I've now cold-restarted the system, so the next lines are startup logs from around 2 minutes later
The second log snippets below show a successful suspend and restart, again beginning at button click
There is no activity in the logs until I wake the system -- this makes sense since the system is suspended! I assume the first set of lines below, referring to stopping devices were just lines queued to be logged.
I tap the power button to wake it up, and apart from the slight confusion around mixed stop/start messages (see above), you can see things do wake up properly
Finally, the system sleep / suspend services report a successful resumption
